What is happening:
When the last item in a stack is sold, the sell button remains. This would make sense if it would then sell items from other stacks (if available) but it does not - it just sits there, doing nothing when clicked.
What should be happening:
When the last item in a stack is sold, the button should either disappear or start selling from the next available stack of the same item.
Steps to reproduce the issue:
Log in, find merchant. Buy something (I chose goggles). Click to sell stack. Once the stack you are working on disappears, sell button will remain.
