I do recall an exploit where a player could emote into a sleeping position in front of , say, a vault or door. And then he would drop clan at which point the thralls , armed with spears would agro on the player but would be unable to hit the player and would instead end up doing damage to the door or vault behind that player. I’m not sure if it was actually considered a cheating exploit or not. Guess I’m about to find out.

However one of the traditional uses of warhammers(irl) was for smashing through doors and makeshift barricades :man_shrugging:

But also , have you checked the event logs? Stand at the affected area, reduce the proximity to smallest and adjust the days passed to include “the day of” and see what the log says. Maybe you have a traitor in your midst. If the log reveals that a clan member picked up a door or foundation then you’ll have your answer. But the filter is key as there are ways to try and bury such acts of betrayal by spamming the logs with so many other entries. Like picking up the contents of whole chests, replacing it and then repeating the action a few more times. That single act of picking up the door could just get buried in there and go unnoticed.
