On Xbox Series X downloaded successfully and installed Dawn of Ragnarok DLC. Managed to play for a few hours but on start up the next day I got the message that Add-Ons were missing and saves were corrupted. Every time I start the game I get the same message. My console recognizes the installed DLC. I deleted it and after a struggle reloaded it. I have tried all of the workarounds and nothing helps.
Any help would be gratefully received.
Many thanks.
