Random crashs: Deadlock detected

[Seadragon91]

@xoft did you already looked at the error

Code:

argument #1 is 'cArrowEntity'; 'const cEntity' expected.

I tested this code in my test plugin

Code:

function OnSpawningEntity(World, Entity)
    if (not Entity:IsMob()) then -- Spawns the error above
        return false
    end
end

Thanks,
