False incompatible version message.

[bluewilson]

Summary
-----------
If one loads a 2.0.77 save game in the 2.1.20-4 client, without saving, then you get an incompatibility warning when loading the save in the 2.0.77 client, next time.

Reproduce
-------------
- Create a game in 2.0.77, and save it.
- Quit and upgrade to 2.1.20-4.
- Open the save game once.
- Do not save it.
- Quit and downgrade to 2.0.77 again.
- Open the save game once more.

Expected
-----------
Game loads without any warnings

Actual
--------
- Warning dialog appears, saying that the client cannot load a save that is newer (or the opposite, the client is older than the save).
- Game continues to load, and plays as before. Appearantly.

Update, as I managed to load the game once more, and get the same message:

"Loading blueprint storage failed: Map version 2.1.20-4 cannot be loaded because it is higher than the game version (2.0.77-0).. Backing up current storage to C:\%appdata%\Factorio\blueprint-storage-backup.dat."

I guess this relates to the player's settings, and not related to the save game at all.

Ticket can be closed.
