The Box Truck variant of the W900 will deal damage to both Players and Zombies while it's on - despite being parked. As of writing this the Box Truck has just murdered me with three fractures to different parts of the legs, all I ever did was mount/dismount from the vehicle. I have no Lua scripts or anything to give to help other than the account I've given, all that I know is I'm very frustrated by what should just be a parked car, ruining my entire playthrough. I have no idea if it's just the Box Truck variant of the W900, but I do remember using the Semi-Truck variant with no issues. Please address this soon, because never will I ever go near a W900 again and I urge other users to STAY AWAY from these trucks until the problem is solved.
