SO, i went to GE and put a dragon g kit for sale for 600m. After i confirmed the trade it instantly sold it for 1gp even thought i confirmed it with 600,000,000 offer. I have NO IDEA how this happend and neither do i have any proof since i don't record my gameplay. Im pretty sure this was a bug.
Edit: Im hoping for a refund since 400-600m item is a lot for a player who only pvm-s.
