Hidden Content: You must reply before you can see the hidden data contained here. I know nothing about this, but you should still make a support ticket. Only admins can help you with this, which is why a support ticket is the best place to get this solved. If you have any videos or timestamps of when these trades took place provide that in the support ticket. If you don't have any additional questions I'll be closing this since no one here can help you with your issue. It's admin related. If anyone else has a similar issue, make a support ticket as well.
