However, in-game the vehicle is only affected by the GravityCoef value.
Directly fixing this issue may cause problems, so I propose this part of the solution: a new hidden value. It would load a certain value depending on how the vehicle was loaded:
- When loaded and value doesn't exist: init as 0, and set AccelCoef and ControlCoef to 1, only with TMUF and Stadium archetype
- When created: init as 1
- When saved: set to 1
