I was playing 0.B (windows + tiles) yesterday and ran into a similar issue as The Lone Badger in the original post. I posted it here since it might very well be the same problem resurfacing.
There was a mansion near my starting shelter and I headed there to pick up loot. Once I had circled the building and killed all the Zeds in the corridors and the 8 outlying ‘M’ squares I headed inside. One of the doors on the center ‘M’ was already partly broken and furious thudding and whamming could be heard. After waiting for a while to see if the zombies would finish the work on the door themselves, I e(x)amined it to find out that the door was listed as ‘partially broken door’ (or words to that effect). But when I tried to (o)pen the door, the game told me that it didn’t exist. After some more waiting and listening the dead folk ineffectually trying to get to me, I decided to give them a hand and (s)mash the door for them. One hit caused the door and the door frame to disappear and the roof to collapse on my character. I was using a mace I found in the mansion, but if it wasn’t something like the Grond (I didn’t check), the effect of the blow felt more like a bug than an intended consequence.
I haven’t yet played the game again so I haven’t tried to see if the same thing would happen again.
