hey @MojangSupport im having some very annoying issues, im trying to fly out of this hole and everytime i try the game crashes or disconnects me from the world (which is a single player world) saying invalid move player packet received, any ideas on how to fix this problem?

Let us take a crack at it! If you could, can you let us know what platform you're playing on? ^BT

i think i fixed it, i removed optifine and it stopped crashing
