Can't delete floating foundation tile
So, I remodeled my Sims house when they came back from vacation. Their house previously had foundation and as I was getting rid of it, two tiles won't delete.
When I was messing around, I found out that I can place items on there without moveobjects on but not a stage (I could put a stage in the space in between them if I put foundation there tho?) so I think there's something stuck there but I can't find it.
I read
this thread and tried the suggestions there but nothing worked for me.
Any assistance appreciated! I really want to avoid moving them to a new lot.
