Update 1.3 Broke Add-Ons

[BigPapaGert]

After the update any saved games or new games created with the add-ons enabled resulted in a "Content Configuration Validation Failed" message. Disabling all add-ons allowed me to create a new game using original leaders and civilizations. These new games would still work after enabling add-ons since only original content was used to create the game. I verified the files via steam and it came back okay. Also uninstalled the game and deleted the civ folder in AppData the reinstalled. No change. Any thoughts?

For the saved games from before 1.3.0 you should join the legacy mode on steam before launching the game. It's under beta options.
