In multiplayer mode, the third user state will not get recognized after the game is closed and reopened. Example: Primary user starts the game. Second user joins in. Third user joins in. Third user gets armor and tools from first user. All three users adventure together for 45 minutes, gaining experience points. All users sleep in beds. Users all quit the game. The primary user exits Minecraft, then all three users decide to play together again. The third user spawns in the world spawn point instead of where they were when they quit previously. The third user has lost all their armor and tools. The third user has lost any experience points previously gained. If the third user had tamed a wolf, it no longer recognizes them.

This happens consistently in one world, but hasn't been tested in other worlds on the same tablet.
