@JuniperWhimsy Unfortunately, that degree_tracker error really does not go away. It's likely to keep popping up every time you load that household. We've not seen evidence that it permanently corrupts a save, but I will say that if you run into it enough it because hugely annoying -- I finally started a new save as I seemed to be constantly running into this in my previous one (but it was a modded save and had had at least some Sims cheated in it, and had some Gallery Sims as well, who might have had a uni cheat used on them at some point.)
As for causes, there is a chance that it's mod-caused if any mods are indirectly affecting anything in the degree. As noted above, Gallery Sims can be a cause as well as there's no way to tell what cheats were used on them at some point. CharityCodes has a mod on Nexus that might fix the issue, but it's not been confirmed to work recently and it may not work on all causes of the error.
Otherwise, your options are the MCCC fix or to roll back your save to before the error began.
