so i've been building up a colony planet, and wanted to build some rather big houses in one area. However, when i put up tenant deeds in the 3 houses i've built and decorated they keep saying the houses are unfit for tenants. i've triple checked every house for holes in the walls and roof and background, and can't find any. all houses are well lit and have doors (i made sure not to use doors from mods in case that was the problem), and yet i still can't get any tenants to move in (i just get the red X). is there a house size limit? or some other necessity for tenants to move in?
