[Condo] Placed items no longer function

I can’t interact with or even collide with any item I have placed. I noticed this when the floor I was building with suddenly didn’t have collision anymore.

What happened

I am basically banned from doing anything except placing things initially and editing them via the Item Finder. Notably this only seems to affect my Seaside Villa condo. Going to my Tower condo does not have this effect, so it’s possible something I placed recently caused the issue.

Check with the item finder at the top right and look for something that has a massive or negative scale, then stash that item.
