well most times the bot gets closed down its either a disconnect from the server or the bot cannot communicate with the minion auth server. So if WTF isnt set up correctly "choose a stable path" then when WTFast switches you over, you will get your bot closed out. Same goes with out running it. If you have a poor connection and have packet loss and cannot communicate with the Minion Auth server then you will get a bot that closes out. the bot tries about every 5min to comunicate with the auth server.
are you running the GUI_launcher or are you using the attach bot button?
