createProjectile crash

[StreetFighter163]

I have created a resource for attaching missiles and bombs to vehicles, however the client of the player who has fired some projectiles sometimes crashes after the projectiles have exploded.

Server code:

  
function addVehicleBomb(vehicle, xoff, yoff, zoff, key) 
    local attachedBombs={} 
    if getElementData(vehicle,"bombObjs") then 
        attachedBombs=getElementData(vehicle,"bombObjs") 
    end 
    local bombObject = createObject(1636,0,0,0,0,0,0) 
    attachElements(bombObject,vehicle,xoff,yoff,zoff) 
    setElementData(bombObject,"bombAvailable","1") 
    setElementData(bombObject,"bombKey",key) 
    table.insert(attachedBombs,bombObject) 
    setElementData(vehicle,"bombObjs",attachedBombs) 
    triggerClientEvent("vehicleGunsChanged", getRootElement(), vehicle) 
end 
  
function removeVehicleBombs(vehicle) 
    if getElementData(vehicle,"bombObjs") then 
        attachedBombs=getElementData(vehicle,"bombObjs") 
        for index2,bomb in pairs(attachedBombs) do 
            destroyElement(bomb) 
            table.remove(attachedBombs,index2) 
        end 
    end 
end 
  
  
function addVehicleMissile(vehicle, xoff, yoff, zoff, key) 
    local attachedMissiles={} 
    if getElementData(vehicle,"missileObjs") then 
        attachedMissiles=getElementData(vehicle,"missileObjs") 
    end 
    local missileObject = createObject(3790,0,0,0,0,0,0) 
    attachElements(missileObject,vehicle,xoff,yoff,zoff,0,0,-90) 
    setElementData(missileObject,"missileAvailable","1") 
    setElementData(missileObject,"missileKey",key) 
    table.insert(attachedMissiles,missileObject) 
    setElementData(vehicle,"missileObjs",attachedMissiles) 
    triggerClientEvent("vehicleGunsChanged", getRootElement(), vehicle) 
end 
  
  
 addEventHandler( "onVehicleExplode", getRootElement( ), 
    function() 
        local attachedBombs=getElementData(source,"bombObjs") 
        if attachedBombs then 
            for index2,bomb in pairs(attachedBombs) do   
                setElementData(bomb,"bombAvailable","0") 
                setElementAlpha(bomb,0) 
            end

        if attachedMissiles then 
            for index2,missile in pairs(attachedMissiles) do

                setElementAlpha(missile,0) 
            end      
        end 
    end 
)

    local attachedBombs=getElementData(source,"bombObjs")

        for index2,bomb in pairs(attachedBombs) do   
            setElementData(bomb,"bombAvailable","1") 
            setElementAlpha(bomb,255) 
        end      
    end 
    local attachedMissiles=getElementData(source,"missileObjs") 
    if attachedMissiles then 
        for index2,missile in pairs(attachedMissiles) do

When i comment out both createProjectile lines, it doesn't crash. Is there a problem in my script or is this a bug?

common bug - projectiles explosions are crashing clients sometimes..
