Unique tab duplication bug

I found a "Blackgleam Fire Quiver".

I have a Uniques stash tab that I bought in the store. I pulled that up. There were a couple of shields displaying that I put in there earlier.

I control-clicked on the Blackgleam to put it in there, and it put it in there alright, but it didn't remove it from my inventory.

I went and disenchanted the one in my inventory and I still have the one that was duplicated.

That's about all I can tell you about it.

Oops, this is a POE2 bug.
