Runs arround ladders etc

[outphased]

Hey guys, i got a huge annoying problem. Very often (like 2/3 ladders holes etc) my bots runs close to the hole, rune arround there for 1-2 mins like it cant find the waypoint and then just finally go down. This slows dont my exp/h like fuck and my profit. Dont know why its doing this.

Is anyone else exp. this problem or know how to solve it?
