I was messing with some of the cvars, trying to get a higher framerate. I saw a command that looked interesting, so I typed it in the console. None of the building's physics worked. I typed in another command, and they were magically fixed. Obviously, I am not going to post the command. If a mod would PM me I would be more than happy to tell you what the commands are. I have seen someone use these about a week before, as well. Now I know how they did it.
