Brief bug summary: When trying to drop/sell items or mesos a message pops up saying 'Items or mesos cannot be moved. Please contact customer support'.
More details: This bug appeared last week, not to all players but a significant amount of players, along with this, we have been taken off rankings.
Character name: GIaced
Character level: 235
Character job: Luminous
World name: Reboot
Date and time of the incident: 12/20/17 around 7pm pst in my case, apparently some other users got this trade block before or after that date.
I'm aware there's already a discussion about this matter but I'm trying to format the bug report as suggested by Invulgo, I hope I was able to do so and that this matter is not only being looked into but fixed soon enough.
