When I'm on the server put firework, then I have to put it is not moving, you can only move left, as if to move forward and press the right mouse button to put firework, then I'll go, if you go to the right and put the firework that the server is shut down, and then it had to reboot, because I can't get to it, and the other players too, need to fix it, because after all this, I don't even moving can't put a firework. (I was on my server, and in a single game all works fine, only on the server).
