I've been through the same issue but in a military structure :
I crounched near a bed at the first floor to get an item placed beneath it, picked up the item, and then I closed the inventory, standed up, seen for like half a second my character floating near the bed. Then I seen the messages "My leg is in pain", broken, blaaablaa and finally I was dead.

@Albrat you're talking nonsense. I used the firestation ladder bug last week ... and there wasn't any information about the new "innovation". You are either a troll or an idiot, sorry about that.

Some friends and I have been into the military structure, to the first floor. I ran near the bench, just after the stairs to get items around, and then I was dead. when echap, I seen my body outdoor the building, laying on the ground. I think I kinda "slipped" through the window, even if I didn't ran into it. I've seen zombies make the same mistake on others buildings lol :) They were dead, laying on the ground outdoor just like me.

NB : We didn't ear any gunshot.
