Yesterday, while in Survival mode, I couldn't get back to my base because a huge chunk of world was missing. I then got a "Minecraft crash" message referring me to a file that's not in my computer (User/AppData/random/yada yada yada).
I haven't been able to get in, since, though the Mojang server says everything is fine.
I can temporarily get into Creative, but either way I eventually get a new MC crash message.
I expected to see more of the same in the issues, but I guess it's just me.
Any thoughts out there?
