This happened to me as well during my first rime in Feast. The game gives no information or instruction whatsoever. I grinded for so many hours and made it to Diamond Wolf and when the seaaon ended I took a break from the game, satisfied with my progress. When I camt back I did not get rewarded my title or qolf collars because I didnt log in to speak to the chit NPC. After that, I never did Feast again lol.
