Thankyou very much, glad you're enjoying it :)
- That's very strange about the chests refilling. I'm actually having trouble recreating this problem with the chests myself, they're working as intended as far as I can tell, I'll have to do some more playtesting to find that bug.
-Yes! In fact the main focus of the next update will be fleshing out the NPCs a great deal, they will even be able to give you Quests :)
-Full documentation for the game is definitely on the to do list.
