This may or may not be some kind of late-game thing progressing so… Possible spoiler warning? Hence why I put it here instead of bug reports.
I’ve been avoiding cities for the most part and have had dynamic spawning on, and as I wander around I’m noticing odd piles of rubble, destroyed buildings, things in general I didn’t do and to my knowledge wasn’t close enough to previously for zeds to do damage to.
The piles of rubble are in seemingly random spots, and have no items inside, nor special monsters. Is this a future planned event or something?
