Thanks for the report! I've fixed the issue so redownloading or refreshing the web game should fix the problem.
As for right clicking in/out of the stash, I've added the right click out of the stash for now. The inventory itself doesn't have any functionality like this since right clicking uses/equips items everywhere. I've added this feature to my ideas list for now, lets see if/when I can implement moving items from the inventory to things like the stash with a keybind.
Thanks for the quick fix!
I ran into another, slightly more serious bug, while playing earlier. I started combat, but the enemies, I believe, all had 0 health. I was zooming through them super fast and my Lvl rose by like 10 levels. I panicked and shut the game off hehe.
I wasn't paying attention to what triggered this, as I panicked too quickly, so I apologize that I can't be of more help. If I run into it again I'll try to be more analytical.
I got over 1,200 leather scraps in a matter of seconds.
