Not messing up for me, what npc are you fighting I'll help. Most likely a setup/configuration error. Best way to use the script is to start near the npc, select npc via nearby, draw a fight box (F7) key, select only fight inside the box, and voila
Turn off quickprayer otherwise the bot will turn on quickprayers. The bot is not programmed to touch any prayers unless selected in the setup window.
Also I have a feeling you're botting in full screen or responsive mode, I highly recommend setting up the classic resolution for best results. Please confirm if you don't have this enabled because all the problems are pointing to that.
