**Starts ripping hair out**
I've tried everything to get my vehicles i've placed in igor to show up while I play!

I'll start by placing a tank or humvee.
Then make a script for it.

Trigger: PreAction

ShowThing: Tank
ExecutePlanVehicle: Assign 'Plan_Tank Moves' to 'Tank' and Execute.

Along with other actions that i can't quite think of atm.
I'll save, play the mission i've created, but it won't show the tank. It's like I never placed it.
And I know i'm playing the same map I created, because I made it snow.
Any help would be extremely appreciated. I've been trying to get this to work for the past few days, and have given up because I can't think of anything else to try.
