So today I noticed that when I transfer an item from IA in to stash I have multiple issues.
1 - If I do not have duplicates of the item (meaning only 1 available), the item will not disappear from IA. Even if I re-open.
2 - The only way to get an item to disappear from IA is if it has the “transfer all” option. The problem with this though, is that if I have 2 items available it transfers in anywhere from 6-26 items.
