Cannot complete campaign missions

/New Beginnings/
I’ve completed the task of /exorcising imps/talking to /archmage/
Accidentally abandoning a post-quest / something to celebrate / unable to receive a quest
Friends share tasks with me, and I can’t complete them, and there is not a single animation
Nothing can be found in the NPC quest location
And I didn’t use the portal myself to fly to the world tree of the centaur plain on my own
Now there is only one / to celebrate / and / the green dragon mother and daughter / goodbye
This is a wrong task
