Is he the only character you’re having trouble with? I wonder if there’s an issue that’s being caused by the fact that he’s the free character, currently.
Unfortunately, if you’ve already tried uninstalling and reinstalling the Season 1 pack/character and done a full power cycle (by which I mean completely shutting down the console and unplugging the power cable for a couple of minutes), the only other thing I could recommend would be to delete your profile and redownload the cloud-saved copy.
I will tag @rukizzel and @GoogleMyName for you here so that they will see the thread, but I’d also recommend posting this issue in the following thread as well;
Sorry I can’t be of more help!
