There are many place on other maps with that kind of bug. You're stuck between the door and something else (Objects or wall) and if you force to get out you are ejected. The fact is that your body stay at the same place but you feel free. At that moment you can walk faster, open a door even if others can't see you... It's like a bug door but i don't know if you can arrest people.
It can't be fixed i think.
