Game crashes when respawning, world restarts and generates differently when rejoining the world

Well, pretty simple. I was slain by 2 baby zombies, respawned and then tried to look around, my turning stopped just when I started then pretty much crashed from there. When the game froze the last thing I could see was unloaded chunks and my igloo basement. When coming back into that world I was where I was again just before the zombies killed me. Then I respawned and crashed again. I managed to escape the next time and got to my igloo and it was back to it's state before I touched it. And my farm disappeared. The chest had restarted with different resources too.
