[0.17.10] Lost whole blueprint library

[Impatient]

Today I updated to 0.17.10 and all blueprints were gone. I restored the backup file, but that was from ancient times. I am really angry and frustrated about that. I made a lot of bps.

Today I first updated to 0.17.10 then back to 0.17.9 and forwards and backward and forward again, because I was joining different multiplayer servers. Then I noticed that the BPL was empty. Shocker! My BPs? And yep ... just the ones from like 3 months ago were in that backup file. Fabulous!

Do you know how much time I spent with blueprinting? More than actually palying the game.

Note to myself: Have a script that periodically makes backups of the BP game file.

Suggestion 1 to the devs: Make more backups of the file.
Suggestion 2 to the devs: Store the file in the steam cloud.

Do you by any chance store the BPL in those hughe desync reports? I have 2 ~400 MB desync reports in the factorio folders.
