Database fix.
Automatic backups for save game data in case there's ever a catastrophic failure.
This is a minor update which addresses a potentially serious issue which could have affected people playing Star and Serpent Solitaire on two (or more) different Steam accounts. There was a non-zero chance that the save game data could have gotten corrupted in a specific circumstance involving Steam Cloud Saves and switching between different Steam accounts.
When you launch this new update the old database will get migrated to folder(s) named after the SteamIDs. The old legacy database will remain in-place for backward compatibility reasons, but it will no longer be used after the migration is done.
For you as player everything should just keep on working seamlessly and there's no need for you do to anything.
If you encounter any issues with this update, please let me know.
