Hello ! I am jonnyboysayhead, as you probably know, and recently I have been working on an epic project with the archaeology mod, a dinosaur zoo! It's sort of based off Jurassic park, although I am not copying the entire map because I'm just making a zoo. So first of all I had a Pterosaur, (although it isn't a dinosaur, it lived in the Mesozoic and it is closely related) then another non- dinosaur, a plesiosaur, and then I added a brachiosaurus pen. while I was waiting for the brachiosaurus to grow, I decided to make a lab type thing. so I made it and finished it, and when I went back to check on the things in the zoo, They were all fine. but the brachiosaurus had grown so I realised it needed a taller fence. while making the fence taller minecraft crashed, and it just said, 'saving chunks'

It had happened to me before, so I just exited minecraft and then opened it again. I loaded the world. 'saving chunks'
I tried lots of other times, but it just came up with saving chunks again...

It took me a while to make the zoo, so if any of you know how to fix my corrupt world, please help!
