well it is due to Kill Pid call that is done when losing connection, tho closeing minionapp does not prevent server to kill Pid when key runs out of time, and key running out of time Always happens at the worst times

Understood, but key expiration and an in-game error are 2 different things and handled by 2 different mechanisms.  MinionApp communicates with the bot and maintains a heartbeat, for lack of a better term, and when the heart stops beating MinionApp kills the game client process.  My best guess as to how key expiration is handled is that the bot is told when it expires when it starts, or the bot contacts the server to validate the key on some interval, I'm not really sure.
