Awhile back I remember on SRO. A developer for bot-cave had a feature that allowed people to record custom pathing scripts from town to destination. The issue with acts after 4 is they require more interaction. I've done plenty of AHK scripts, lua and altered a few different hacks and bots. I wouldn't mind helping out with the pathing scripts if you guys want to implement them sometime. Food for thought.
Something I also noticed is in some maps the bot gets stuck on narrow walkways and 90* degree turns. Due to pathing distances between points. These small things kill me because you will end up watching the bot spend 10 minutes stuck on a corner doing 180's trying to get to that next path point
