Each of my colonists has their own room. They all have the same items in each of their rooms. One of my colonists has a -15 for being envious of another’s room. I tried fulfilling something on his bar of what he wanted in his room but he wanted the shelves for food in his room/house. I put one of each he requested directly in his room and nothing happened. His mood is continuing to go down so I can’t remove one of the needs either. I am not dragging pre-built items. I even went so far as to delete my originals and build all new ones and nothing has worked.
for envious you have to put thing with “beauty” on the room till he’s no more envious ^^
