Hello!
I recently encountered some serious problems when using multiple behaviours.
I noticed that they very offten colide with eachother and break the desired combination of behaviours.
I would like to propose to 
Ashley and 
Tom to allow us to chose and set behaviours hierarchy.
Curently we have in behaviour selection window option to move particular behaviour up or down but i did not notice any functional difference (correct me if im mistaking).
Could you guyz set behaviours hierarchy acordingly to their defined position in units behaviour window so that second only work as long as it dont breaks the logic of the first one... and so on... and on...
I think that would be very helpful in creating some complex behaviour combos.
Thanx!
