I might be the only one that

@Stormkeep I've no idea! I can't figure it out since I don't decorate anywhere. The game just does it by itself even though I deleted all the holidays now. I tried to put a deco box on the lot but it wouldn't let me do anything because I don't own the lot!

I suppose I could go around to every commercial lot I have, make them residential, and send a sim around to remove everything? It just looks awful.
