You will need to regenerate your config for this update. This is the last time this happens.
Added an option to the config to set which slot you want the captcha item to be given (only in the captchas that require an item)
Added an option where the last item the player had will be saved and will be returned once he completes the captcha to prevent item loss.
Fixed an error in the color captcha where it would not work properly and it would send colors like magic or strikethrough. Also limited the colors and their names to make this simple.
