2nd Player Data Loss

When playing split screen, we paused the game to take a brief break. Player 2 exited the game whilst player 1 stayed in, but simply paused. When we returned, player 1 was in the same location as before, and had everything as before. However, player 2 was now considered a "new player" of sorts, and as such spawned in at the world spawn with absolutely nothing (but a map, of course). We tried exiting and coming back into the game, saving and loading the world, and rebooting the system, but all with no luck.

As a side note, autosave was disabled.
