Are adjoining doors, AKA doors between two directly touching buildings working as intended? Or are they a bug? I made a colony that used this "Feature" a lot, and I noticed weird behavior. Notice on the left side, the dormatories for the lower class. The connecting hallway is also a lower class bunkhouse. They can't actually path to those rooms for some reason, the one closest to the main area disintigrated because nobody with the upkeep trunks could reach it. You can see confused colonists with upkeep trunks wandering around right south of the dorms, trying to find a way in. And here is a bug, as you can see the doors open up into a wall which can be walked through. Is that just an oversight, or am I breaking the game? To make adjoining doors, build a building, add doors, and build another building right next to it. The door will let you pass from one building to the other. You cannot make a door once you have built both the buildings, which is either a bug (If adjoining doors is a feature) or intended (If adjoining doors is a bug). Just thought I would share some of the insanity.
