'Can't intersect other objects' when nothing in the way
I've been having an issue with items not being able to be placed in some locations. When I try to place an item there, I get the error message "Can't intersect other objects." That's nothing new, but as far as I can tell, there is nothing in the spot.
See the pictures in the comments below for one example. I'm trying to place this modular shelf. I had a different in that exact spot a few minutes ago and I wanted to replace it with a different shelf. but suddenly I can't put anything in this slot. I can't see anything in the way. I tried moving the light just in case that was causing some issue. I don't know what else it could be.
This has happened in multiple lots in this save (my household and a community lot I'm building) both on walls and on the ground.
I'm on PC. No mods ever in this save.
