Strange the Bugbear is telling you to bury an Item or Weapon yet you don't have any in your discard pile so it should not have triggered. Thanks for the report.
Strange freeze indeed, thanks for reporting this! If your first party is not working, try deleting it (the characters will return to your experienced characters pool) and you can create a new party with those characters.
We are getting reports of players letting their game idle for long periods of time and having their saved game be corrupted. (the load party screen shows a jumbled party and characters are getting cloned) You should be able to do this, however until we can figure out what is going on it'll be safer for you to quit the app between gameplaying sessions.
That could just be random luck, or that could be an issue, we'll be looking into that more. Also try swiping as da-mayor suggested and let us know if you still have that issue.
This is something that we want to have in the game and would like to try to do. While we don't have a timeframe for it to be done at this time, do know that it is very much on our radar and hope that it is something we can get to you all!
The Gallery shows all the adventure decks and chest cards you own. This represents your collection
The Vault shows all the cards that are used in the scenario you are playing. The Vault represents the physical game box. If you were playing a deck 2 scenario it would show all the cards up to deck 2.
Very odd we'll look into this, if this happens again please snap a screenshot. (Tap a card during the discard phase and show that there is not discard button)
