Today I suddenly had 3 Darkmoon weekly quests completed according to Savedinstances, while Darkmoon is currently inactive and starts in two days. I assume these are the quests I did last Darkmoon and the timing is off because of the new year.

SavedInstances version 9.0.4

And not wiped after Darkmoon started. It's lots of bugs, all around darkmoon tracking actually. I'll take a look at this if I have time.
