Alright so I've made one mystcraft world, and it was a mess. So I left, then I threw the descriptive book into a trashcan deleting it. I made a new world, and when I spawned in I crashed immediately. I've reopened the save multiple times, and all I can see around me is a field of obsidian, and I may be in a crater of obsidian. But then it crashes immediately.
So I have put the log onto pastebin, and if anyone could help me figure out how to fix this problem then it would be much appreciated! It is stopping me from playing on my world
And my last backup was at 11 am this morning, so I'd really love it if I wouldn't have to roll back to that.
Here is the log:
