I was on experimental branch on steam but I have a lot of problem with 2.0.73 and blueprint library is one of them. now I can't have my library in 2.0.72.
117.513 Error BlueprintShelf.cpp:637: Loading cloud blueprint storage failed: Map version 2.0.73-1 cannot be loaded because it is higher than the game version (2.0.72-0).
117.532 Warning BlueprintShelf.cpp:659: Loading local blueprint storage failed: Map version 2.0.73-1 cannot be loaded because it is higher than the game version (2.0.72-0).
Is this normal ? cause that very annoying when you have bugs in 2.0.73. Blueprint are mostly string they shouldn't be affecting by non major version of factorio no ?
Is there a way I can export all my library and import it again in 2.0.72 ?

Yup, this is one of the downsides of using Experimental versions, especially with Steam Sync enabled - the Blueprint library is upgrade-only. I tend to just stick with the Experimental track - it rarely blows up, and the new
bugs features are fun to discover.
You can look for the blueprint-storage-backup file.

doesn't work for me since backup and current is the same file since I go several time between both version I guess.
I don't get why there is not a backup for each version if this behavior is normal, I even have backup of 0.17, I will never opt in for experimental version again, wanted to help to test it well never again.

My advice is to never downgrade Factorio versions.
It happened to me as well, I used
viewtopic.php?t=94427 to get my blueprints back (had to put everything in the same blueprint book though).

I didn't lost them, I already have export all of it in strings, my current problem now is I need to import 98 blueprint by hand.

Honestly it's a very big problem of factorio I will never upgrade again, that very annoying when most public server stay on stable, I lost all my blueprint, I have weird bug

Factorio should made a backup of blueprint by version not just major version if there are incompatible with previous version, or at least keep a "last stable" backup version, and should also warn user when a save is override with an experimental version. If they want tester for experimental version they need to help on theses matter.
I doubt we will have a stable version before long or even before 2.1 so now I'm stuck with 2.0.73 I need to manually import 98 blueprint I guess

If you frequently play with different versions of the game, the only advice we can give is to use one or more portable zip installations and manually backup and copy blueprints between them. I never use the personal blueprint library because I change installs/computers so often. I use the "game" library which goes in the server save file, or store blueprint strings in github.
