So I'm tweaking and optimalizing my jail escape, fixing some bugs etc. One bug is a set of decorative doors closing every round while they are supposed to stay open during the entire host. I've found the culprit by looking into the save file, and it appears to be a 1x3x5 brick.
Now I can't seem to find this brick ingame since I have no idea how the .bls file works, and the mission editor pulls one of those 'drag a window around and it leaves a trail of windows' errors whenever I open it. Any help would be much appreciated.
