Today I just realized I just lost dozens of hours of work making blueprints into my game library, just to disappear out of thin air after reinstalling Windows.
It makes no sense that the Steam Cloud Sync is on by default but not this option.

Had a very similar thing happen half a year ago or so, thankfully had a backup of a save file where a lot of the blueprints were ingame, and pulled them out of there. Was a nasty surprise to me as well.

I had no such luck. All the save files did sync properly, except the Blueprint's because of this setting. And since I erased the entire computer before installing Windows, it was all gone with no backups available. They should atleast warn the player about this setting since most probably the player will just assume the blueprints are also being saved, like I did.
