Ok, this was the trickiest to fix. It was flaky bug which on top of that ended up having several different ways to reproduce, which needed a separate fix for both of them. So bugs were
- You save with stack in village inventory, you update the page, after load you can't take anything from inventory which soft locks your whole progress with not being able to finish the Craftsman quest
- You have a stack of something in the game and then you add a map card on top of it (most likely a dungeon map card on top of stack of remaining stones). This breaks too, now map somehow broke the stone stack and your inventory stopped working. Softlock again
Im afraid there could be more cases I haven't found, but I fixed those two. Inventory works differently too, now you can take the whole stacks of same items from it, which is more convenient then taking out the whole stack of stones one by one.
Could you please check again (most likely need to start a new game) and say if the bug is still there?
