Player0 spawns into a vehicle deletes player1's vehicle

So, this happens me all the time now, and i cant figure out why. I modified the spawnmanager so players get spawned into a car instead of on foot, BUT. Every single time, player1 respawns, player0’s vehicle despawns. I tried everything, settingentityasmissionentity and all stuff.
You can join my server Rain’s race server and take a look by yourself.
How is this possible?
Player2’s vehicle looks independent.

I literally spent 2days debugging this, and right after i posted it here i found the solution.

SOLUTION:
Use vehiclespawn like this
CreateVehicle(vehicle, spawn.x, spawn.y, spawn.z, spawn.heading,true,false)
If you have the last argument on true, by some reason it glitches and removes the 0th player’s vehicle.
Otherwise its fine.

Where did you edit this? In mellotrainer? cl_vehicles?

no its my own script.
