Heal problems you are having are due to bad Color-Maps. So re-creating your color-maps in the bot is what you need to do. The bot takes pure colors from the windows screen buffer, so it doesnt matter what monitor calibration or color-enhancement you use. I would reccomend you re-watch the tutorial video and go over your config and color-maps again, that will fix the heal issues. It works for everyone else.
About stuck: with any bot in any game, botting is always about location, location, location. Short for lvls 86-94, there is always an alternate location you can use that is pretty good for botting. Noone complained because of stuck issues yet, so you need to find a spot that works for you.
The go to town is something I would like to implement myself, but its not easy, I might put some efford into it in the future, no promises tho.
Range limits - impossible with this bot, because of the way this bot works, discussed before.
