I am 100% completion of all the SC2 campaigns (except all the new 10y anniversary stuff) but Nova has been stuck at 95% even though I’ve done everything.
Specifically Dark Skies achievement and that additional achievement that unlocks when you do all the side missions. Neither of them are earned, even though I have completed them multiple times.
edit- I also noticed that WoL campaign is at 100% completed but it shows that I have no score on any of the challenge missions. As well as me beating all the missions (and side missions) on Brutal 12 years ago, yet some show incomplete or only on normal.
