So the games listed as S. America are locked for Cis region or even SEA Region,
https://dispenser.tf/market/4113/

i Bought 1 and got SEA Lock
the game are on my bot so Joto can revert the transaction id:
6251683
bought from:
A+ Bot Shop

Okay, the transaction is reverted.

We are investigating the problem as well, it looks like the content of the gift has changed after the trade is created, as it only happens on GRID 2.
