Here is a link to a crash report. i cant post it on here because of character limit. Factorio crashes every time i try to convert any of my last 5 saves in map editor. i can convert older saves no problems (3 or 4 days old). Ive checked for mod updates which hasnt helped. https://www.dropbox.com/s/5...

Just had this issue myself. but there's a way to get it back on single player. load a previous save with the book, copy string, load most recent save and import blueprint book string. problem solved:)

Tried changing the version in info.json but game wont load. any chance of a fix?
