CrimeCraft GangWars achievement is impossible.

It is impossible to get the CrimeCraft GangWars achievement for the Bolt Action Blitzer. The crashes within 5 minutes with Steam client because it detects the Steam client as some kind of hack. Also if you play the game and close Steam it says "Server offline hack detected". I just want the hat because the game is shutting down on 31st and you won't be able to get it again.
