Two bots in one area, one goes crazy

Why is it when I have two bots working in the same area, though usually Mists of Pandaria locations, one bot loses its mind and proceeds to not exactly fly, but more stick to the ground like a ground mount and even choose to swim from one island to another when it is perfectly capable of flying?

Settings on both are the same and trying a different profile, reverse pathfinding or not proceeds to give the same result. I mean with the new leveling system this is quite abhorrid due to it sticking to land and running through as many mobs as possible to just reach one node. 

Is it just not possible to run two bots in the same area without causing one to lose its mind?
