Object Manager locked unfolded


Hi, I was looking around in the menus of the Object Manager, and next thing I knew, the +/- switch to Fold/Unfold groups and hierarchies stopped working in this particular file. All the groups are unfolded and they won’t fold. I’ve tried selecting Fold All and nothing happens. It works in other files, but stopped working in just this one file. I tried restarting the software twice already, still the same. Anyone have any idea what might be going on? Thanks!


Looks like no one else has seen this problem before, but in case anyone is looking for the answer, the only thing I could do was to copy and paste everything into a new project. My guess is that one got corrupted.
