Player data backtrack, world stays the same
While in the nether i was making a bridge of soul sand an soul soil, i accidentaly threw an ender pearl and started falling into the lava below me. I very quickly with fast reaction time saved and quit... when i rejoined after about 30 seconds, i was about 2.3 Hours backtraked with my inventory as it was in that state about 2 hours befor... but... the bridge i built was still there(the world remains the same)... even though it saved me... this is still a bug that could lead to disssatisfaction to other players (if it happens to them) P.S the bolded text are the key factors of the bug... Thanks for fixing further bugs

5minutes later...
I HAVE MADE A NEW DISCOVERY!!... now whenever i join the world it resets to the same position it did the first time, ONLY THE PLAYER GETS RESET the items on the floor dont, aka INFINITE DUPLICATION GLITCH

I have found a way to replicate this problem... if someone has an .nbt file for data open, the world doesnt save properly and the player data is reverted
