Click button twice for pathfinding?

[attachment=0:m5h5cgn4][/attachment:m5h5cgn4]Hello;

I have a button -- start path The first click nothing happens, the second time all the tanks start moving. Why do I have to click it twice?

Thanks for your time

You can't call Move until the "On path found" event is triggered. Add that and it will work.

Thanks blackhornet. That fixed it.
