Many Vehicle.GetHandling() setters crash game
Description of the problem
Game crashes if using too many vehicle handling setters. Getters are fine. For me this happen after changing 2-5 handling values.
Reproduction steps

Expected behaviour
Game should not crash.
Additional context
Values are default, taken with theVehicle.GetHandling() for sultan, so there can not be something wrong with values or might be? I found in discord that there might be problem with setting many handling values at the same time which causes game crash https://discord.com/channels/371265202378899476/576771706119520287/870921686042697749 From my test I found out that the game crash is not 100% garanteed, but more likely 90%. Sometimes game doesnt crash until you restart game
