I'll take a look at the bugs on screenshot 2 and 3.
EDIT: I can't reproduce the bugs. Can you help me out? Do you know how to get the doors stuck? I couldn't get it to work on my test server.
The bug on screenshot 1, can you explain how it happens? Can you force it somehow? Can you tell me when it happens? I'm aware of the bug but haven't ever experienced it myself.
