Shedu Part Missing From Inventory

[(NSW)Xair]

Finally got a fourth shedu part to drop, had it on the rewards screen (made sure I picked it up), got back to the dojo and only had 3 parts.  Didn't return with restart like missing rewards normally do.  Sent a ticket to support and they closed it saying there was nothing they could do.  If rewards screen drops aren't safe there isn't much point to playing until we get patches, sure hope that lich update is worth the delay in leaving the newest content near unplayable.
