Hello, everyone!
We've been made aware of a recent issue where players are having trouble redeeming loyalty rewards between physical disc copies of Mafia III and Mafia II.
For example, in Mafia III Lincoln has access to some of Vito's wardrobe, and later, when unlocked, can access new vehicles through the garage.
NOTE: While playing the physical versions, if any Mafia title is completely uninstalled along with the save data, Mafia III may not be able to detect this data and unlock these rewards in-game. However, if you have deleted both saves and game data, you can try reinstalling Mafia to recreate saves, and the other titles should then be able to find them and unlock these rewards.
