I lost my follower, and know that the Dragon Seeker Quest from companions will do it, but I have now done 15 quests from Vilkas and not gotten a single one. I think I had one when I first join the companions(several hundred hours ago, but I don't remember). I have completed all companions quest, and all Totems for Aela. I am no longer getting any quests from Farkas, and have completed the Purity quest, though I met the bug where you go with Vilka back to that ancient Companions place and it instantly auto completes without you going inside(don't know if that's relevant.

I also tried completing all the quests that were started when I got the follower. If it matters, I think my follower was a young male mage from the College of Winterhold.

I also read that your follower will return to his spot after three days of waiting, but I don't see him in the College of Winterhold.

Is there other repeatable quests that not the Dragon seekers quest, lol? As many as you can find plx.
