I would also like to understand when this will be addressed? My son has been forced to play offline because of this issue since launch. I control what he plays and based on the fact that offline and online gameplay are identical there is no reason to not let him play with this friends. It curses like crazy in solo mode, what are you protecting him from by staying offline?
To make matters worse he just purchased the Gorgon DLC and even though he has the email bill, and the Xbox store confirms the purchase, the game refuses to let him play as the monster. It tells him it’s locked. Any matter of uninstall and reinstall does not resolve the issue.
