FIXED Crash when loading track with specific kart (QUESTION)

Most tracks work, but some specific tracks crash the game when played with my kart. For example, Skyline works just fine whereas Dyson Speedway crashes when trying to load. When I try playing Dyson Speedway with a different kart, it works.
Every time it crashes, I get this:

SuperTuxKart crashed :/

SuperTuxKart crashed!
