- I can't turn in my Inn/Tavern daily quest
- The NPC for my Inn/Tavern daily is missing
The daily quests from the Lunarfall Inn and Frostwall Tavern need to be turned in the same day that they are accepted. The next day, the Inn will cycle its' patrons, and a new set of quest givers will arrive.
If you've completed the criteria for the quest and cannot locate the quest giver, it's likely that they have left for the day. You'll need to wait until they return to your Garrison and complete the quest on that day.
Remember that there are 3 floors - the ground floor, the second floor, and the basement. Some quest givers may also wander around outside on occasion.
