Current infestation mechanics?

[Cellar_Cat]

According to wiki these should be spawning under "overhead mountain" near base structures, but this does not appear to be true anymore as I've had them appear under a constructed roof outside of the mountain as well.

They give you a warning now. The game keeps track of areas mined out, but starts the infestation elsewhere

[Cellar_Cat]

I'm not sure what you mean, like it shouldn't spawn where I've mined at all?

In this case I had dug into a mountain and used it as a refrigerated storage. There was a small area near the coolers where I knew they could spawn, and some did appear there, but also others appeared further out into the base which was under a roof I had built between my structures.

The OP's story checks out. I just instigated an infestation via Dev mode:

https://steamuserimages-a.akamaihd.net/ugc/964223454749531644/763FF89A6038E3488AC8C4B588023EE58E93B710/

Only one of the 5 hives spawned in an "overhead mountain" zone.

I reloaded, laid down some carpet and tried it again:

Carpet no longer stops them from sprouting up. And neither does furniture. They busted my 3x3 table with one hive and popped up through the carpet in several other spots. They are more obnoxious in how they spawn. You can no longer manipulate the spawn points by loading furniture onto the overhead mountain tiles, they will simply bust through them. Smoothing tile no longer seems to affect them either. Tynan is sending a clear message with this one; you build under a mountain and the infestations will come.

Insects spawn in any mined out spaces from an overheated mountain area.

The only way to prevent them from spawning is turning that area into a freezer. I think it has to be -5 or lower to prevent them from spawning. Anything else at best just acts as fodder while you get your pawns into positions.

This was mostly design to discourage only mountain bases since those give a natural defense against other forms of raids.

I had small outdoor space with overhead mountain where i mined some resources, next to my crematorium.
Well they spawned both under the overhead mountain and inside the crematorium.
I presume it was because they could not spawn in the open and since there was ♥♥♥♥♥♥♥♥♥ of them, they used that room to spawn the rest.

Second time they all spawned inside the ancient ruin i had put home area over.

In the past they Only spawned under overhead mountains. Keyword being only. You could dig in a shallow amount under the mountain and never have them bother you since you only built under the thin mountain roof. Now they will spawn in tiles that do not have overhead mountain roofing. The case being that they have a longer range on their spawn zones.

Yes, it seems to work like overhead mountain being the startpoint, then the spawn zone spreads out from there anywhere there has been a mountain/hill before.

It extends beyond the thin roofed areas too. In one of my screenshots they appear in my living room area which is plain dirt flooring. No rock flooring there, which is new.

They will also crawl up your Deep Drill no matter where that is. Very frustrating. Had to make a kill box just for bugs while I drill up some plasteel. Have not had them show up outside of the overhead mountain yet other than the drill incidents.

I hate the bugs!! LOL

[Cellar_Cat]

I don't mind the drill so much, it's at least predictable. A cheap turret or two seems to help there because they melee it to death and... boom. Doesn't kill them all but makes it easier for colonists to finish them off.

Yep my kill box around the deep drill has 4 corner turrets. ;) But it is a pain to have to put turrets in the corners of your freezer.

I will say it is fun to use molotoves in a marble bedroom and burn them. When I do explore tunnels looking for resources I put marble doors on the entrances so I can chuck in a molotov and burn baby burn. :)

I have always found infestations to be the most unfair aspect. I know most people feel this is true about tornadoes, but I really really hated infestations prior to B19

Now however they give you ample warning prior to arrival! I can actually evacuate areas.

Typically I compartmentalize the base into burn-rooms. I just torch an area and rebuild OR sometimes I will chill the entire base and/or large areas.

You can stil affect the chances of spawning at a given place. Temperature / Darkness still has bearing.

Yeah, I don't mind them enough to disable them or anything, just surprised to find it acting this way when it wasn't written anywhere that they can spawn in a radius around eligible areas.

They can also spawn in natural caves. I had a infestation in a cave in the other end of the map.

Another thing is, is it only in my game that raiders seems to pick out hives to attack instead of the colony itself?

Yeah, I'm sure this isn't new, they spawn near an overhead mountain area. Presumabably they come out of the ground as much as out of an overhead mountain. So, in that area. It doesn't give a specific spread for how far they spawn outside of a mountain, and now you say the wiki says under an overhead mountain. I'm sure when I was looking it up somewhere it was clear the mechanic was that it spawned in a area around and including these square. So, I don't think this is new this release but for quite a while now.
