I didn't actually expect anything to happen, I was taking a cruise with my elytra.

What actually happened was...:
The game crashed, I'm not entirely sure why

Steps to Reproduce:
1. Make a new Minecraft World (Hardcore)
2. Crash the game (intentionally only to test, does not need to be intentional to trigger the bug)
3. All unlocked achievements/logged statistics (distance flown, # of mobs killed etc.) reset for some reason while everything else in the save was untouched.
