I did it on Europa. I still have a few more Heritage tokens but I don't feel like burning them all to help debugging knowing they won't be replaced
The altered wing armor vanished about 4 or 5 seconds after the conversion while I had put it in a secure chest, so there may be some trick to avoid the bug, like locking it down, or sending it to bank through bag of sending, but again I don't feel like burning all my stuff to test. Maybe after server stops saving during maintenance if I can manage to be online at that time.
Note that I tried on Test Center before and had no issue, so I don't know what exactly causes the bug.
Now of course I'm annoyed to have lost my quiver, but what annoys me even more is that this bug had been reported months before and apparently nothing has been done to fix it.
