Until recently, I haven't been playing much PoE or completing Queen's bounties. Now that I've been running some PoE, I discovered that the treasure keys that were already in my vault cannot be retrieved nor can I send keys to the vault. Obviously, this means I can't transfer keys between characters either. The players I've joined from LFG have also reported that they cannot retrieve their keys from the vault either,. In their cases, most of them weren't able to open the chest at all, but didn't realize it until it was too late (e.g. we were in the treasure room). In my case, I've been fortunate, since each of my characters has at least 3 keys. Given the timing, I think this change may have happened during the argonarch rune fix to prevent it from being transferred. My hope is that the change was unintentional, as I don't see the same value of restricting treasure keys, like the argonarch runes. I don't remember seeing any mention of it in patch notes at any time. Also, my searches have not turned up any mention of changing treasure keys either. Please fix! Thanks in advance.
