Why The Witcher 3: Wild Hunt and The Witcher: Wild Hunt – Complete edition are different games in my Library?

Hello Xbox community!

I’ve played Witcher 3 via Game Pass few years ago and finished main story. Game pass version doesn’t include DLC. So after few years I decided to buy a game with all DLCs.

But what a disappointment it was when I discovered that the Complete edition and main game are separate games. This version has separate achievement tracking and does not use the save data of the original game.

Is it possible to merge save data and achievements? 👀
