Submitted two tickets over this and I can't reply to either one, so I'll explain and warn who I can here; hopefully everyone is more careful than I apparently need to be when dealing with this personal banker.
I was in the middle of using my personal banker that you purchase in the crown store, Tythis Andromo, when instead of depositing my Telvanni Maces motif and an unknown blue recipe, my character Doctor Peppuh consumed them instead (04/16 11:20pm EST). Turns out Tythis Andromo moved while I was in the middle of using him. It used to actually kick me out of that window when Tythis moved, but now it's keeping the window open without allowing me to use him and basically behaving as my inventory instead of a banking window, causing me to unnecessarily consume items I'd like to instead deposit. So to whoever uses him, be careful because you may end up using up losing valuable consumables.
I honestly doubt I'll get either of these back, since I don't even remember what one of them was (blue recipe), but I'd like to at least warn anyone else that this bug is happening and you can accidentally use valuable consumables.
There is already a
bug thread about this, but I think people should be more aware of this bug. Especially because no one at ZOS has replied to it.
