I'm not sure if this is an actual bug or not, but I have a event that triggers something. However, it only triggers if it's on the trigger is behind the switch. Example if it click "Bring to back" on the switch, it doesn't trigger the door. However if it click "Bring to back" on the switch then click "Bring to back" on the door, it works. I'll recreate a cap if need be.
Actually, I think it might the containers. The if I bring the door in front of the switch, the container outline box disappears, if It put the door behind the switch, it reappears.
