Glad you're having fun!
As far as the work in the guild goes, all you need to do to proceed is to assign all available adventurers to a quest. If you don't have an adventurer fit for some quest, then don't worry about it.
I will try to make it more clear in the game in v0.1.5, as well as potentially adding a "finish early" button.
Consumables are broken in v0.1.4 and I have a fix ready for it. I also intend to redo the trading menu completely (if not now, then at some point). Thank you for the reports :)
