Realm will fail to register some blocks as broken or placed as well as fail to display chat messages. Soon after, the game will claim to have timed out. The realm will appear to have players on it even though it just kicked them all off. At this point, players are unable to join the realm. When the server catches up (typically 5-10 minutes later) and players log back in, progress will be reset 10, 15, sometimes 30 minutes. The problem seems to arise when another player tries joining the game, or when another player goes through a portal in-game. Note: This problem also occurs occasionally while only one player is on, but it is much more frequent with multiple players.
