This shit is awesome.

I´m adding this here, maybe other users will need it.

• No working when minecrafth is in other laguages (Only English Uk in my case)

Thanks.

For "not working with language setting other than English" part, I think it's about F12 automatic reconnection.
Because locating the back button to detect and exit error screen is done by image searching with back.png sample file,
the script would fail to notice disconnection when the back button doesn't show the English word "back" on it.

By changing back.png with your button image it would work again.

I will update the readme about that Soon™.
... Or maybe adding GUI to it to make this program more usable on free time.
