I was in skyblock. I was having issues with dual monitors in another game so I shut dual monitors off and went back to normal mode.
I alt tab every minute or 2 between fights so check for zombie villagers and kill any other hostile mobs.

As soon as I switched back to single monitor I Checked Minecraft and I got a crash report. I tried restarting the game several times but kept crashing. Restarted computer crash.

When I got back in after a free reinstall, and switched back to dual monitors. I was dead and I lost all my stuff. I was in a safe place lit up well. I place myself inside a box when I go afk so that this doenst happen. Even if its for a minute like it was in this case.

Whatever the game crashed caused me to die. I can't explain the death as there isnt like a combat log.

Is it possible for a roll back as this was clearly caused by an error, as my game crashed, I should have immediately also been logged out, safe and sound.
