Big bike bug?!

[Atti]

function bike_setupRandomSpawn( ) 
    local bike_vehicleModel = 400 
     
    if not bike_vehicleSpawn then bike_vehicleSpawn = { {x=1, y=1, z=1, r=1} } end 
    local rnd = randInt(1, #bike_vehicleSpawn) 
  
    fadeCamera ( source, true, 2.0 ) 
         
        local playerveh = createVehicle( bike_vehicleModel, bike_vehicleSpawn[rnd].x , bike_vehicleSpawn[rnd].y, bike_vehicleSpawn[rnd].z, 0, 0, bike_vehicleSpawn[rnd].r ) 
    setTimer(spawnPlayer, 500, 1, source, bike_vehicleSpawn[rnd].x , bike_vehicleSpawn[rnd].y, bike_vehicleSpawn[rnd].z+3 )  
    setTimer(warpPlayerIntoVehicle, 1000, 1, source, playerveh ) 
end 
addEventHandler("onPlayerJoin", getRootElement(), bike_setupRandomSpawn) 
  

I removed everything that is not necessary. Here's the problem: the player spawns, but after few seconds the game stops refreshing, and all slowly become white (such as with an over-50 gravity). Music continues playing, but tha player can't move.

Such a strange problem... A lot stranger, when i managed to spawn out of my bike (a BMX). Taah-daah! Everithing goes perfect. And when I spawn a BMX with my admin panel and I enter it... 5 second and again that bug!

I dunno if it has been already asked, but I haven't found anything.

Can anyone help me?

The 'whiteout' bugs are associated normally with bad positions or bad rotations. Check you're setting correct values.

I've tried... but i'm spawning at 1,1,1 and also when i try to spawn a BMX from the admin panel it does this bug.

EDIT: I ask you only one thing. Try it and report me if you get any bugs. I actually CAN'T cycle in MTA, i always get this crash. It takes only 5 minutes, plz try it!
