The bot runs backwards from azomodan's room to the waypoint in the core of arreat. you should get the checkpoint there before starting the bots. I don't remember if it comes with a normal mode version but it's an easy change..
<GameParams quest="87700" step="-1" act="A3" difficulty="Nightmare" resumeFromSave="True" isPrivate="True" numGames="-1" />
Find that line in the profile and change nightmare to normal if it doesn't. saves as .xml and loader up.
Great ! your awesome
Thanks!
