Thanks for comment, i found bug (problem with round value) soon i will upload new version od game with fixed saving progress, new weapon line (crossbows) and stash :)
unfortunately, the the game didn't save when my laptop died (not sure if there ever was a save feature or anything. if there was, it didn't work for some reason ._.). but it might have had something to do with the blacksmith. but might i suggest making the selling click and drag to an area in the blacksmith window?
