looks like worldgen bug

Seems to be two cellular dungeons colliding which is usually incredibly rare (meteorite dungeons only spawn in like 1:15k chunks anyway), still there's probably a way to prevent that.

I had similar crashes on a Crucible public server where different structures were mentioned in crash log (don't remember which).
