The realm that my brother and I play on has suddenly become very laggy and in the past two days has kicked us off multiple times, and then proceeded to essentially revert the world to the state it was in about 30 minutes prior. Personal internet is not the issue as everything else on his internet is working perfectly fine, as does everything else on my internet (two separate houses and not the same internet). We can't actually make any progress with how much it kicks us, forcing us to restart either the application, the computers we are playing on, or both, before it resets the save.
