I did play The Witcher 2 on xbox 360 2 years ago, and I have 32 of 50 achievements completed with 545 Gamerscore.
today I did move all the save games on myxbox 360, from the internal HDD to the Cloud, then I restared the xbox 360 console to let it upload them.
After that I see that the save games appear on the cloud "in sync".
Then I downloaded Witcher 2 on xbox one and run it.
Then 2 major problems appear
1)the game loads on xbox one but there are no save games to be found
2)when I check the achievements lists from the emulator I see 0/50
I did turn on my xbox 360 and I see in the achievement list there that The Witcher 2 appears 2 times in my list
one with 32/50 achievements and one with 0/50 achievements .
I idid press "Delete Game History" on the 2nd game with 0 achievs but it didn't help.
