Very small issue but I wanted to report it none the less.
If you right click a door and "lock" it, the game changes the door graphic to have a lock. However, when you reload the map, the door appears as normal again, even though it is "locked" if you right click on it.
Solution: when the door loads, check if it is locked, and use the locked door graphic.
