Not sure if that's it, but I see that it's trying to spawn a vehicle with model 193.. Model 193 is NOT a vehicle, vehicles start from 400. My guess it that it screws up because you're spawning an invalid vehicle model. Try searching the script for that AddStaticVehicle(193, ....); or CreateVehicle(193, .....); or perhaps in your saved data which might be loading the model 193 into the vehicle loading part..

EDIT: 193 is a skin, to be precise, this one:
