Triggers not working on spawned units

[TEL79]

Now I got the scoring working as intended using the OnActorDead, thanks to Kodiak.

Now if only there was a way to get those spawned units to cause triggered events. I still don't understand why the scriptspawned units can't trigger the ArmyRedGround pass through triggers while every non-spawned do. How do implement a pass through trigger using the code?
