when you come on a server and has selectet wrong kart it`s not possible to change the kart on the server. also not with reloading the server with right kart.
You get always the kart that you have select in your first connection.
Same thing here. I am not able to change my kart. also, the game crash during load times.
It is not a bug.
If you reconnect then race number, name, kart and paints are restored.
Ok good to know, Thank you piboso
