Character Name: oynx Problem: Forfeited quests stay "In Progress" and couldn't be removed. Details: Currently I have 3 of those: "Maria and Shanks", "Maya and the Weird Medicine", "Legend of the Snail". The quest item disappears but the quest itself remain listed as "In Progress". Probably you could run a database clean up for quests that are in this weird state (i.e: reset the state / remove progress)?
The problem also happens not just on forfeited quests actually, also on a quest that has been completed. It doesn't get removed from "In Progress". I completed the quest "Warm El Nath", received the rewards but then it stays in "In Progress". This bug is a bit more difficult to reproduce.
