Uhh can I put a wall on a habitable area?
Nope! When those habitable areas are calculated the first time, you've essentially drawn lines to create the walls to tell you how many squares it is.
Thanks for playing!
Oof guess that makes it quite hard to build larger habitable areas thx for awnsers. I also am gonna work on 2- 6 card mini expansions later today and where's the best place to share them do you have a discord?
