On targeting i have "others", it means bot will attack other monsters if trapped and will use exori, this happened to me aswell sometimes. You can change it on targeting.
If you look on windbot where you see the features, look at pathfinding options, does it say "walk with arrow keys" ? If not then change it to walk with arrow keys.
And about the waste, sorry, but profit here is purely based on luck XD
There is no reason at all for bot to get trapped, i've tested it myself for over 12 hours before and nothing bugged for me :l
