just found that u can actualy jump out of a already shutted room, like the gas chamber, i dont think this should supppose to be happen so i assume it was a bug.
This is a known issue afaik, been happening since patch 0.2.1. The crusaders jump pack skill also causes this.
On a side note it is a nice little gimmick to be able to get out of the gas rooms if the doors bug shut on you.
this bug also give me some idea, maybe way should not limited to only one way to deal with some traps like the gas chamer, just like now we can just destory the door or jump out of them, maybe more methods to deal with it in the future
