Floors and walls breaking bug
So sometimes walls and floors will just up and vanish... or so it would seem when you miss what is actually going on and only get there when it's over.

When I launched the game, I caught quite a few of my floors and walls (didn't have the thought to take a screenshot immediately) shaking, indicating that it didn't have proper support (I felt dread as so many were shaking and it would royally screw me over if it all broke... there was stuff on top of it) before it stopped and went back to normal, indicating it was now all perfectly good (my current concrete floors are on top of a (1 tall) single elevation of concrete pillars (quite a few to make sure most floors are anchored), quite a bit of the structure being above water.

It looks like sometimes the game bugs (especially when loading into a game) and does not calculate structural integrity correctly.
This isn't the first time it has happened as when I don't catch the phenomenon, it sometimes just leads to me finding walls or floors missing randomly (which is just great considering how resource intensive, and thus time consuming, building with concrete can get when it's those that break). Sometimes the floors and walls in question are directly placed on the ground.
This has happened with all materials types I have built with (except for thatch as I barely built anything using that so didn't get to see it happen)

I can't possibly be the only one experiencing this right?

I've had similar issues as well. Floor looked fine but when I plopped a crafting station (usually a Concrete Furnace when I start out building with wood) it would break the floor.

I learned that my structural beams were actually not going IN the ground.

So do try to ensure that the structural beams are actually connected to beams which are in the ground. Most likely they are not.

I recently built a Scoria floor on the ground, put beams and floors on top of that and it turned out that they gave no support because the beams had to have in-ground support even though they were pretty much on the ground.

I've had it happen to me with walls disappearing on several occasion and in almost all instances my furnaces were directly touching the pieces. Since then I've started leaving more of a gap between the wall and the furnaces (all types) and haven't had a disappearance since. Yeah it's nice to have things tight up against the wall to create more space, but I'd rather not have the concrete wall disappear and my electric furnace disappear during the next shower.

There's some weird interaction between deployable pieces when they overlap. For example just the other night I put a fireplace in along one of my walls. It snapped right into place and let me place with no errors. Right over the top of my herbalism bench with a mortar and pestle. Which were now directly inside the fireplace. Both now showing no shelter. So the first shower would have destroyed them even though they were inside a fireplace, inside fully sheltered room, inside a sheltered cave.

Yeah, this is the exact thing i posted about earlier that happened to me. It's like sometimes when you load in, the building part isnt attached to where it should be, so it thinks there is no foundation and breaks.

As I said, the walls and floors started shaking in the usual "whoa, bad structual integrity" and then stopped doing that (nothing breaking). It was right when I loaded into the game. It was basically saying there was a problem and then stopped, which is obviously not how it normally goes. When structural integrity is not good, you can just watch as what you just placed down breaks. You probably wouldn't even have time to place anything on top of it.

My beams are also well into the ground, that is not the problem. Like I said, it randomly happens and often times replacing the floor or wall that vanished doesn't really cause any problems after that.
I think certain object clipping through (like crop plots) might also throw integrity calculations off (had one wall constantly vanish, and it had crop plots against it, but the other walls around it that also had crop plots clipping into them were fine though...). Furnaces seem to love breaking walls too.

I'm used to playing around with structural integrity, not just in Icarus, so I know how to place buildings into the ground haha

Yeah, I noticed how walls sometimes broke because of the furnace. Happened to me within hours of starting this game and haven't done that since. In this case it was weird, most of the tiles and walls that started shaking had nothing on them (I had just, that very second, loaded in too, it was really weird). Luckily it didn't break, though I lost the flooring piece that was at my doorway (and fully on the ground too, perfect structural integrity since it was one of the first pieces I placed. It wasn't one of the pieces that I witnessed shaking)

I really think that that's what is going on. I often load a game and then 20 minutes later quit to character select (or completely exit the game. Loading times are pretty short, at least on my computer) because I have to do something, and sometimes repeat that a few times throughout a session.
All the loading back in might be why I see an abnormaly high frequency of that happening.

OMG that's so annoying, it's still a thing apparently.
I try to put a concrete wall, but then it starts to break. I quit the game and restart, the wall is ok, but after a few seconds it starts to break again. So I quit again and restart. Now it seems ok, the wall stays in place...

Structural integrity sounds nice in theory but it's useless if the engine can't support it. They should just remove it let us build anything.
1) For such complaints, it would be a good idea to start by showing a screenshot that would clearly show where the problem occurs.
1.1) I hope you don't use mods.
1.2) Everything is fine with structural integrity in Icarus; this did not stop me from building a 10-11-story castle made of stone, everything stands and does not fall apart.

Structural integrity is in a pretty good space right now I think. The problems you run into with it all have to do with having massive bases on an Open World map.

First that the giant base causes a baseline processing increase. This extra load leads to the normal area loading process as you move around spiking your CPU which causes the late game stuttering everyone complains about. Before you have that massive base there is enough processing overhead that the CPU spike isn't even noticeable so you'll see much better performance in a fresh mission.

Another problem is the map loading. There is no structural integrity saved state, so when the full size Open World map loads there is a huge processing backlog that has to be slogged through by your CPU. If your base is too big your pieces might sit wobbling because they don't have any structural integrity info yet and possibly even break before the first structural integrity check is actually completed.

I've never seen this happen but I assume it is possible and may be what Jdwarfer was referring to - placing a piece would require a fresh structural integrity check for it and it checks the rest of your massive base in sequence before getting to the new piece. While waiting your new piece may break before the check completes.

That's why I always recommend keeping your Open World bases to a more reasonable size and saving your massive pave the world base for an Outpost map. The Outpost maps are much smaller (4sqkm vs 64sqkm - each map grid line is 1/2km) so right from the start the base load is much lower and all the resources respawn fresh on a map load so anther large part of base load is removed there. That leaves a much larger part of your CPU overhead for base building.
Jdwarfer May 15, 2024 @ 1:22am 
So is that massive?
If it is, then I say the structural integrity is bad. That's my opinion.

And that ruin was my temporary shelter that I left when I built the concrete one.
That's high quality structural integrity right there lol

1) Personally, I also have a lot of different opinions, especially regarding player comments on this forum.
1.1) ‘Load-bearing structures’ in Icarus are only beams and foundations (maximum capacity for concrete foundations 20-21).
https://icarus.fandom.com/wiki/Concrete_Beam
https://icarus.fandom.com/wiki/Concrete_Frame
All other structures are elements ‘consuming load-bearing capacity’. Concrete (vertical) walls too.
1.2) In the first screenshot, I see you have concrete walls stacked one on top of the other on three floors. The fourth floor, apparently in the middle, cannot stand it and is destroyed.
1.3) In the second screenshot I see a destroyed wooden structure that was destroyed by bad weather. What's surprising here? Building elements need to be repaired regularly, this is part of the game. Only concrete is immune to the elements, but can burn in lava on Prometheus.
Judging by the upper right corner, you are playing Olympus (medium difficulty). In this case, your maximum weather level is yellow with four petals. It can easily destroy wooden structures and cause minor damage to stone ones.

1.4) Beams (even wooden ones) and foundations are impervious to bad weather.

1.5) In your case, in the first screenshot, you need to “stitch everything” with concrete beams along the perimeter of the building, at the corners of the building from the very bottom of the ground and vertically upward.
I posted my screenshot above (number two), which shows that even my castle, made of walls as thick as the foundation, was forced to “sew it from the bottom to the top” with concrete beams for additional strengthening, since on the 10-11th floor the load-bearing capacity of the stone ones was no longer enough foundations.
Concrete beams, if placed vertically, by the way, have the same “load-bearing capacity” of about 10-11 floors.

Haven't played the game in a while, but i'll still respond to Jdwarfer, then will unsub from this discussion thread (I really thought i'd already done so).

What happened to me back then wasn't structural intergity issues, it was just me loading into the game and the walls and floors shaking as if there was a structural integrity issue before going back to normal.
Only occured when I loaded in (lasting for just a few seconds. All of those structures were on ground floor with most floors and walls placed directly on foundations) and none of the structures ever broke from what happened, ever. Sure it was worrying, but it was always fine and only ever occured when loading into the game.

The screenshots seem to just show bad structural integrity, as far as I can tell from just this.

As long as a structure is in contact with the ground it can act as "load-bearing" which is why, last I played, you could build with just floors and walls if you wanted to, no foundations or pillars needed, as long as you didn't make anything massive of course. Floors have a maximum range from a load-bearing wall for example, same with stacking walls, there is a limit. Buildings, especially those made of wood, will be damaged during storms and need to be repaired. Abandonned bases will degrade over time, again, depending on the material.

Also don't worry too much about potential perceived passive aggressiveness you might read on this forum, especially from the more active participants.
Jdwarfer May 15, 2024 @ 3:28am 
Yes, that's a bug anyway because when reloading, the walls stays in place without breaking.
I understand the maximum capacity thing, but it's not noticed in the wiki. So thanks for that, it might me usefull, but there's still bugs. And those bugs are my concern here. And it's linked to the structural integrity.
I find it very annoying, that's it. I don't think I'm overusing the building capacity of the game. I build simple things. Anyway I stopped wishing about beautiful constructions lol because IMO the result is always ugly xD If only there wasn't those visible metal parts inside the concrete wall... I chose concrete only because of its durability and resistance against bad weather and hostiles. Well... in theory it can be broken by wolves, which I find ridiculous but nevermind, I can cope with it xD
It's just that building in this game is frustrating for me, mostly because of those bugs.
