Preferably, your quest would end at around the same time as others. I make it pretty clear when a quest is ending. Although, a guild member having returned to the headquarters is a clear indicator that any other quests should be wrapped up soon.

However, extraneous circumstances can derail and make quests longer than it should be. If that happens, just let it happen. I'll take care of the other things.

Also, added something minor into Eilidh's update.
