Well i guess i found the first bug, maybe...
I had two characters hunting, they logged out when stamina was over. One of them logged back in again, but the other one was trying to log back in with the first character. I will check again if it is going to occur to me again.
Well, I clearly explained that when you login for the first time, you must delete all existing characters data in client and login by entering your character name, password and world.
When you open another bot, do the same -> delete all existing saved characters and bla bla bla.
BOT connects to the first saved character with saved password.
