I'm honestly not sure why this happens. Had someone else report it too... However, for me, even if cloning a fresh version, it doesn't break for some reason.

Are the scripts visible in the menu/selector if you try to assign it manually? (behaviors are named the same as their GameObject)

[Albeoris]

Yes, scripts are visible.
I can add Game Manager manually and it will display correctly.
