Persona - autoswap and items disappear

Swapped between my 121 Druid and a 15 Rogue persona a couple of times to optimize the item places and then each 3x round cut opal and round cut emerald disappeared. This is highly critical. I had enough space in the bags. I used persona before with no such a problem. The only difference could be that I changed to the old UI in the options->display->"use new UI Engine"-tag because the quest journal sometimes simply does not open anymore with the usual key bind and since that change to the old UI I don't have that quest journal issue again. But despite that this should neither happen to the old or new UI.

Scary stuff. They should find another system besides "dump them in the nearest open bag and hope for the best".

It seems it is not related to the UI-Flag. I forget to take out my bag with my L121 gear and didn't untag the "autoload and autosave" buttons (with new UI flag).

1. changed from 50 to 121 -> without swapping (without auto-buttons)
2. changed back from 121 to 50 -> with autoload/autosave buttons (without gear in inventory)

Result:
Despite I had all gear which belonged to the L50, the system kicked out a single augment (Mesa Hardstone from Ornate Consigned Chain Boots).
The functions seem highly bugged. I cannot imagine what the system accidently does to my precious stuff (L121). The storage on this L121 is catastrophic (so no safe testing possible without any stuff in the inventory). I can only empty two bags for that toon to work with that persona.So far only augments disappeard or getting kicked out of the slots. It seems my Artizan's Prize and other precious ones are still there but checking that after every change is really annoying. This needs a serious correction.

Another one:

Arrows are not put back completely into the Ammo-slot with autoswapping while switching personas. Only one is put back.
