Ok, so originally, I was going to keep this bug (found by accident) very private to discuss with a developer at EHG… until I logged out and found out that the bug is completely ‘visual’ and is not actually ‘duplicating’ items in the process. In other words, the bug happens in-game yet it gets ‘undone’ once you log out and back in.
However, even though the bug is a false alarm (thankfully!) the ‘Stash tab’ duplication bug is still a real thing (just without the duplications of items). Also, it appears that a single Stash tab can be duplicated like this 1 time per tab. In other words, the bug won’t create more than 2 copies of a Stash tab.
Here was the first video I created that lead me to believe ‘items’ were also being duplicated:
And here is the second video I created that shows that the ‘dupe bug’ is ‘visual’ only:
Thank you for looking this bug over. Please fix to prevent confusion!
