Unable to move furniture in Build/Buy after downloading from the gallery

For probably over a year (possibly longer), I’m having an issue where after downloading a few lots/households from the Gallery, I can no longer move furniture in Build/Buy mode. I’m unable to pick up or reposition objects.

This happens in every save file, not just one. The only way I can temporarily fix it is by deleting the localthumbcache.package file and clearing the cache folders. However once I download more items from the Gallery, the issue happens again.

I have repaired the game and the problem still returns. 

I do have mods and cc installed but they are all up to date and I just don't know how this keeps happening every single time.

Has anyone experienced this before or know what could be causing it?
