HELP!!! Blocks at random locations are starting to fall of!

[farmer.joe]

This is starting really annoy me..

The game is hosted on my desktop computer, and has been hosted for about 4 days now.

There is currently a huge game breaking bug. Blocks at random are starting to lose their "sticking power". I have no idea what causes it and I can't narrow it down at all as to what could be the cause of it. It has been happening to a few structures around an area my friends and myself have been playing. For the sake of explanation, I will focus on a bridge I've built.

I have built a bridge bridge was using the Wooden Frame block with some upgraded to the 2nd upgrade. The pillars are 3 blocks apart. I came to this calculation as it at this distance, even if one pillar were to break, the bridge will not collapse as two pillars 7 blocks apart can still hold the bridge up, making it sorta over engineered in case a zombie hits one block.

Now, the issue. The bug happens at random, I have blocks just 2 blocks in height falling as well, but I will just use this bridge as an example. At some height, blocks just won't stick at all, even if it's just 1 block outwards from the pillar. There were no extra weight placed on it at all, no one. I would just place the block and it would just fall.

Have a look at this screenshot here:

What you are looking at here is the bridge in question, as well as a make shift scaffolding I have to illustrate the issue.

As you can see, the scaffolding I am on has the blocks extended 5 blocks outwards from the pillar. I am standing on the edge and it is holding well.

Now see this screenshot for the problem:

Here are two pillars that is to connect a bridge to a more complete structure to the right. As you can see, the moment I dropped a block at that spot, it falls down as shown in the screen shot. The block can't even hold it's own weight. What gives?



Blocks that tested to be producing the issue:
Wooden Frame, 1st upgrade & 2nd upgrade
Wooden Stairs

This is due to physics. I believe the limit to a branch without proper support is 3 blocks off, maybe 4. There are ways to by passing it, but building ontop of something that's barely supported will cause it to break. Know some physics of how to build something exquisite will take some actual thought of the building. I use this same thing to breaking a lot of ground by digging the lowest lay wanted till everything falls - saves durability and time.

It's hard to tell what works and what doesn't work. I'm not sure on the scripture of the code. Play with it till figure it out is all I got to say XD

Yeah, I know how the physic works, that's why I designed my bridges to be over engineered. You can break one column and it'll still stand.

The issue here is, it can't even branch out ONE block. Check out the 2nd screen shot. Can you see the missing link? That's where I placed the block. And you can see it falling off (different graphics to the rest). That is the bug I'm talking about.

Cheers.

I'm not too entirely sure on that. Tried placing one somewhere else on the support pillar?

[farmer.joe]

Anything placed on anywhere else on that support pillar will just fall. Nothing sticks on that pillar after a certain height. I have deleted the entire pillar and rebuild it from scratch just in case and still it doesn't fix it.

I guess I have to over engineer my designs even more. LOL.

The physics are still broken apparently in 8.7 - this has been reported as far back as Alpha 3. At the farmhouse on Coronado, I've got a number of blocks on the first floor (near the fridge and the stove) which just started to collapse. It doesn't matter what I fill the holes with - as soon as I walk over those blocks I fall through to the basement. (The collapsing floor blocks are immediately adjacent to the foundation wall of the house, so they should be considered 'supported'.)

Some of the blocks are falling from the in game physics. I've had an issue where I was building with the upgraded rebar frame blocks (2nd tier not 3rd). I had a 2x2x40 pillar that was going to connect to the other pillars in the area. Placing a single rebar frame adjacent to the pillar caused the rebar frame to instantly fall and break. It didn't matter which player placed the block or on which face it was placed. It happened 5 or 6 times before we figured out a work around.

We had to build from another block location at the same height and attach the rebar frame to that block. Even though it was in the same exact location (still right next to the tower) it stayed. This isn't exactly normal behavior for the physics engine.

I'm not sure if your wood frame bridge is of the same or similar issue. I do know that wood frames on my server do not build over 2 long without falling. Upgraged wood will extend about 5 or 6 before they fall. The fact that it seems to be adjacent to the tower seems to be similar. There is some calculation that the game is making that triggers the block placed to fall. Have you tried placing another type of block there? Dirt or rebar frame etc?

I wonder if maybe the odd blocks that aren't sticking right are on chunk boundaries. Any chance of doing an lp command in game and getting the coordinates for those who've got such block issues and reporting the coordinates of the falling block?

[farmer.joe]

My blocks falling could have been the cause of my friend building a tunnel underneath. That game was in 8.6 so to check it out and inspect would have been troublesome, not to mention that said structure with the issue have since been demolished.

Looks like the SI takes into account even a single gap from under a support column.

TL;DR
Make sure there are no air pockets below a support column.

I have been running into the same issue; if there is an air pocket which is below ground level, then things start to fall on top of it.
