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
