Account that it has occurred on: Elf Pker5
Problem: Lost untradeables
What items: Grand looting bag, Infernal max cape, Karamja gloves 3, (possibly holy wrench (i) and bonecrusher imbued aswell).
(Sadly i cannot remember everything lost, it's been quite a while, There MAY BE more items lost.)
What may have caused it: I had transferred $1000 from one account to another, and losing donator rank also loses you bank space.
Not sure how to explain it, but it may have deleted certain items from the bank as failsafe.
Hopefully it's just a bug, not my own doing.
