Solved
Only three lot types available in build mode.
When I opened up build mode today there were only three lot types to choose from; residential, haunted house residential & tiny home residential. I don't have all the packs, but before today I had a plethora of lot types.
Does anyone know of this bug and how to fix it?
When someone is living on the lot you can not change to other lot types than residential ones as Sims can not live on the other types.
