patrol etc

hello guys, I have a problem (noobish I think :/) but anyway, if I let units patrol, for u to dodge them, they only patrol once.
They walk from A to B and back to A, then they stop.

I did this: Unit - Order Infernal 0015 <gen> to Patrol To (center of Infernal1 <gen>)

isnt this just supposed to work???

I know I can also use Move To and when he enters region walk back etc but I have a lot of infernals, so that will be too much triggers

plz some help :s thx

I have another question aswell: how do you not let units walk around eachother but just trough them, like they are not there?

and the infernals must be able the walk trough gates, how?

thx

Well to answer the second part, use the Unit - Turn Collision Off action then they'll walk through other units and doodads.
