Portal System Multiplayer

[GabeHasWon]

Summary

The Portal System was merged a week ago or so, and works perfectly (to my knowledge) in singleplayer.
In multiplayer, however, I was unable to stress test it properly and won't be able to for a while.

This ticket serves to make sure the portal system works properly and consistently. Mark off one or more of these tasks when completed many times.
Tasks marked (on host and client) mean testing both on the player hosting the server (if not headless) and a non-host player, especially if running one instance in your IDE and another without a debugger. Sometimes, a host/debugging user has a slightly different experience than that of a normal player.

Tasks

• Placing map on map device (on host and client)
• Using map on map device (on host and client)
• Returning from map subworld (on host and client)
• One player dying in boss domain, repeat until a ghost
• All players dying & turning into ghosts in boss domain

Reasonings

The map device & maps are central to the mod and lack of functionality in them would be catastrophic to gameplay experience.
