I've been building in this world for a while, it's a super flat world.
It crashed when I was riding my dragon towards one of those witch circles, there was a small bit of the ground that hadn't loaded in yet and it started to lag a bit as I came closer. When I rode over it, my game crashed. Every time I open the world, it crashes and I can't fix it. I can't change my coordinates in my player.dat folder as it's literally I giant string of random symbols and stuff.
I have enough memory in my launcher, I checked. If anybody knows how to fix this it will be greatly appreciated!
