[0.17.2] Saving a blueprint irreversibly converts the blueprint library

[Hornwitser]

When trying out 0.17, the existing blueprint library from 0.16 is migrated to a new format if you change anything in it. This causes it to become unreadable in 0.16 (see attached image).

This is bad, as steam users that want to try out 0.17, but then go back to 0.16 is likely to lose their 0.16 blueprint library in the process.

Same goes for save files. If you do not want to convert the library, do not use 0.17 or create a backup beforehand. NaB.
