A list of waypoints can be found https://github.com/ineedbots/piw5_bot_warfare/tree/master/raw/maps/mp/bots/waypoints
There are a few members of the community submitting waypoints to the project over time.
And Bot Warfare is completely external to any of the stock gamelogic, so any unexpected behavior not related to the bots is something outside of the mod.
I run the Bot Warfare Dome server as a testing stage for the bots, so feel free to join that and see what they are like.
If you'd like to contribute waypoints, have a look at https://github.com/ineedbots/piw5_bot_warfare/blob/master/raw/bw-assets/wpedit.md and https://github.com/ineedbots/piw5_bot_warfare/issues/6
