I and my cousins were playing Alan Bond's "Netwars" levelset

However, whenever one of us died it said "Internal error" or something and then we could not continue the level. I guess this is because the player is recreated (because of the 9 lives available) and this doesn't work in Network playing apparently.

I have seen LAN player teleportation cause other players who were not involved to have their view centered on some other place, and then the player can appear to walk off of the side of the level based on the view. But you can't see the player in the view.
