When I checked my notes (I always take extensive notes), I had tried all the things you suggested. It appears that you have to do a few unrelated things in the inn in a specific order. After doing so, I have an empty bottle, but nothing else has changed. I'm fed up with examining and searching and using the same things over and over again, so I guess I'm going to have to give up on this one, otherwise I won't have time to finish the others. Sorry. Maybe I'll come back to it after the jam.
My outstanding issues are:
- How do I get water from the well (assuming that's what I'm supposed to do)?
- Where's the shovel?
- How do I get into the church?
- How do I force the passage of time?
