Re: [FAQ] Why don't my expansion packs transfer between platforms?
@jsimkitteh Hi! Unfortunately, it is not possible to transfer game content purchased for PC or Mac to any console. I think the main issue is related to obtaining the licenses necessary to play the game on different platforms. There is probably also an issue with the different formatting. I'm guessing the code that governs how the game runs is different between console and desktop / laptop versions.
Edit: Please forgive the similar post here. This thread was merged, along with a similar one, into the main thread for this issue.
