Hmm, a couple people have mentioned that moving mods out, starting the game and saving, and then moving mods back in works. I know that's the first thing I tried (and deleted the caches, restarted etc.) and it definitely did not work. Reintroducing my mods brought the bug back in.
But because this seems to work for some, it might be worth trying.
And I know the progress bar isn't supposed to shut off, unless you're talking between terms. After taking finals, and before classes start on Monday, you don't have progress bar because school isn't actually in session. If it's missing at any other time, than it's a glitch. Resetsim seems to work.
