I forgot to mention: My memory of this is a bit hazy, so it's possible that it was an autosave, but I wouldn't be able to tell you where it was. I know it was within the limits of the previous update, though. I'm sorry I can't give a more accurate description.
I believe this glitch is caused by the save loader! I haven't tested it 100% since it's a bit difficult to recreate but jumping between v0.6-v0.7 using the save loader is a bit glitchy given I altered how saving works between those updates. I'm going to try and release a chapter selector or something next update that will help with corrupt save files
