Is it true...?
I recall reading a comment somewhere indicating that if you replace a vanilla vehicle, that does NOT come with tuning parts, it will crash the game if the replacement spawns with the vanilla tuning parts on. Is this true? Also I remember someone stating to remedy this, to change value to -1 for modkits in vehiclemodelsets.meta. The values all seem to be defaulting to zero. Doesn't zero mean "no" to spawning with tuning parts? Why does it take me having to say "-1" to make it a "no"?
I think they spawn on the replaced vehicle just fine without causing crashes, the tuning parts will obviously look out of place though because they were made for the default cars.
