Hey! Just wanted to say thanks for the speedy hotfix, unfortunately it seems I'm not able to get the new version to recognize any of the old versions saves, but it seems to be working just fine with its own save.
As for how far I got, I made it to the first abandoned town on the surface. I had just pushed a boulder that connected to the beginning of the town and the local save point, so I saved there and called it a day. I think I should be able to get back there in about an hour if i rush through everything.
