Cant progress my corruption on any timeline when i get enough stability on some timelines harbinger is greyed out and incomplete timeline is shown. Seen a few reports about completing a normal lvl 90 monolith and still no change. Stuck on 4th harbinger corruption 150 needed. I have screenshot but can add it.
I have the same problem even with Fall of the Outcasts Timeline. Incomplete timeline on all except three I’ve completed.
