No... the map is still pre-hard mode... I am wondering if there has to be any empty floor space in the room? The ones I have noticed all have chests covering the entire floor (except where the table/work bench and chair are)... the doors have 1 space by them to open...
[doublepost=1526530730,1526530188][/doublepost]Ok... I just went through and emptied a chest in a few rooms and removed it (giving 2 empty floor spaces) and now it says it is valid housing again...
I built this world last year and it has always worked fine... but when I visited it earlier I noticed that about half of my NPC's were missing... now I know why... something changed in the housing requirements and now there has to be some empty floor space apparently...
I guess I will need to either make the rooms larger (currently 10 spaces wide) or only have 2 chests per room...
