I'm trying to recreate ring of the wild hunt for my characters iv leveled to 50. I end up recreating it on my crafter, but when i put it in the bank. It completely deletes, and now im out of 25 crystals.
Yes, I can confirm that it is scary at first but reloading ui usually finds my missing items. I use inventory insight so I know what places they are and if they aren't there I do a reload UI and it usually finds it. (or relogging). Your heart will skip a beat though wondering if you lost something.
You can also "transfer" items between characters via housing storage. I have one empty 30 slot chest just for that. It is way faster - since in banks you have to load other player's characters vs housing that is a solo-instanc and it loads much faster.
Just "park" other characters in same house, or in a house with storage chest placed
