Ground vehicles take damage from nothing in Adak Coop

[Zeraaaaaa]

For some reason, all the ground vehicles in the map continuously receive damage (despite running on a flat road, not being shot at, and not ramming into anything).
I could barely drive more than half the map before catching fire and exploding. This is recorded on the map Adak COOP Std and Alt.

Already known and fixed.
