world broken.... STILL cant play

Once again, the world is broken! I made a post about it before, about when i play a worldthe fps is soo slow. Then when i leave and join back the whole world looks like a glitchy mess or something that you would see in Pokemon games when you hack. When i made the post, it said it was resolved, but clearly that was a lie. the first time the game was slow, the second update the game was lagging and slow, now this update the game was slow, lagging and I jump in slow motion apparently. Typically i would say to make an update to fix this, but you guys are soo dumb you guys would break the game anymore. Like seriously you guys do bnot deserve to be working on the game. FIX THIS! (and TEST IT TOO BEFORE RELEASE! hint hint)
