If I load into a save, existing or new, if I enter build mode in an apartment from live mode, undo doesn't work. Undo seems to work on a regular residential lot or if I enter build mode from the map,...
Ideas
could you check dorms and penthouses too ? Maybe it has something to do with objects being saved to one specific apartment/the shared space.
Penthouses, both City Living and Lovestruck, have the undo option. So do dorms, once I enter the freebuildmode cheat.
So do haunted house and tiny home lots. I thought I might as well try them too.
