WWII Car w/ Rocket

I have the rocket jeep set as the reward for the bonus mission for level 7, but when I select in in the phonebooth, it crashes the game (this happens when I actually select it, not just when I scroll to it) Any ideas on why that could be?

So just to make sure, the jeep is set as the bonus vehicle for level 7 in your \scripts\missions\rewards.mfk?
In rewards.mfk, if you didn't do this, you'll have this line:

BindReward( "smith_v", "art\cars\smith_v.p3d", "car", "bonusmission", 7 );

Replace smith_v with gramR_v, so instead of that, it will be:

BindReward( "gramR_v", "art\cars\gramR_v.p3d", "car", "bonusmission", 7 );

Yeah that's all set. The weird part is when I call the vehicle using the "all vehicles" cheat, it loads fine.

EDIT: It seems that the problem was it was obtained as the bonus car, as I changed it to a purchasable reward and it worked fine.
