If its relevant for the first time i had some flamer platoon buildings on the mission, and i wrecked 3 of them before this happened.

@FrostRaptor as i understand, there was an NRE before in ConcreteJungle.Patches.Building_KillLinkedUnits.Prefix, that left a building in an undefined state, and it caused LoS calculations to crash
