I'm having the same issue. I haven't tried to get Great Zimbabwe yet but I redeemed the Amplified 2022 content and can't turn it on. It even shows up in the Windows store as a previous download, but I can't redownload it (or at least that isn't making a difference for the game recognizing it).

I'm glad I'm not the only one! I'm worried about future content that we will miss. Microsoft is asking me to talk to amplitude. But how can I get someone here. We need some customer service rep or something. I tried messaging a developer yesterday so I'm patiently waiting. I have the game in steam as well and no problems there.

I am also having the same issue in Game Pass.  Zimbabwe and Amplified show up, but I cannot move the on/off switch to allow use of these DLC.  I redeemed the code from the Games2gether site, and have account linked to Game Pass, but no luck.

I double checked and I have redeemed both codes also through the Xbox GamePass Profile settings.

I redeemed the xbox codes as well but I still see it greyout ingame. So I'm still trying to solve this.

I do have the same problem. Not working on my Xbox Gamepass

same problem. not work in gamepass

same problem :(

I have a similar problem. I bought the Deluxe edition from the MS Store and the African expansion. I can usually start a game fine, but after I save, quit and try to reload my save file I get the error 'file is using one additional piece of content error'. When I check Extras/ Content Management/ Add Ons I see the 'Deluxe' and 'Cultures of Africa Pack' but I am unable to toggle them on. I click the '+' signs by each and attempt to go to the MS Store to verify but the pop up does not load.

Tried running as admin, uninstall/ reinstall to no avail :-( . So currently I cannot play ANY saved games after starting a new one....

Bump. Still having the issue.
