Can someone explain exactly what these warnings indicate?
- "During upgrade, detected that questions X had instances in quiz Y but were not actually used. The instances have been removed."
- "Because of the previously mentioned problems, sumgrades for quiz Y was changed from 20.00000 to 10.0000000 You should probably check that this quiz is still working"
It may seem obvious, but I don't really know if it's a concern or not, why it's happening, or how to check and confirm that everything is OK.
