Playing on a MacBook Pro.
This error occurs with and without mods and CC. It started in Willow Creek with the community lots, then slowly started to spread to my residential lots in Willow Creek. When I load into the lot via Build/Buy, the lot will be empty, and the surrounding lots I can see reverted back to the base game lots when I had previously customized them myself. If I try entering the lot with a sim, it does not let me and I just get Error Code 800.
