Hello!
Some time ago i have got message from one of my buyers about problem with receiving some items from Gameflip bot. After that i decide to return all items from Gameflip bot and got same problem with 8 items.
Thanks for attention!

Godspeed! 
Yep. I’d opened ticket week ago. But get answered only today. And don’t get resolution for now. Just want to inform other users who use bot trades (sellers or buyers not matter) what there can be a problem.
