Hi,
There are two mixed achievements between DLC in Hitman 2 :
is under "Himmelstein", but it's a "Hawke Bay" achievement.
is under "Hawke bay" but should be under "Himmelstein".
Also, the achievements of the new map "The last resort" are categorizer in the main game achievements, but should have their own DLC (called the last resort) as it's part of an extension (Island and Chill - The Dundee - The Pleasure - Full House - The Platinum Package - Extra Luggage - Null and Void)
Thanks !
Best regards
