Hello all,
Thank you for your reports of this error message while playing Assassin's Creed Valhalla on Google Stadia. I am very sorry to hear that you are unable to properly load your save games due to this, and thus cannot play the game.
Having checked for an existing report of this issue, I can see that we have already forwarded information to the developers with regard to the "your game had a glitch" error, and they are looking into it. Due to the nature of the Stadia platform, we're unable to offer direct troubleshooting, however please rest assured that this is an issue we are aware of and we'll update those affected as soon as we can. I'll look to make a new megathread for this issue with this thread as the primary, so that any players on Stadia can share their experiences here for us to track.
It would be helpful if you could all let me know which quest / world event you were completing at the time of your last save, as well as the region you were in, for me to investigate if there is a common sticking point for those affected. Please make sure to have tested the game on the latest version (TU 1.1.1) to make sure that the issue persists currently. Thank you very much for your help in advance!
