This happened to me as well. I turned on the game and it walked me through the setup as if I had never played the game before. Then my XP and stubs went back to 1 bronze/0 stubs. I then went into Diamond Dynasty and everything came back. From there, I went into MTO and continued a campaign. This is where I saw the authentication message. I was near the end of the regular season with the Nationals. I didn't do anything to warrant this message nor did my system glitch. I continued playing MTO to the end of the season and received this message again before continuing to the postseason. I thought this could have been an issue in the latest update (I updated yesterday right before seeing this issue), but sounds like this has been an issue for at least the last two weeks. Another update was available today, so I updated, but the issue is still present.
