I do understand that air unit deaths will interfere with a mobile Grid. But I see several mobile grids that use Air unit explosions within them, and no matter how hard I try, unless its a unit in the grid thats dieing it just displaces completely. Can anyone help me with this?

The deaths will not interfere if you run one grid per trigger loop within an area. Is the grid you are talking about one grid per loop?

Im sorry for the trouble. I acually did get one of my mobile grids to work with air explosions now.
