Cannot for the life of me figure out how to import faces, logos, etc..
Depending on what you want to do:
1. In an existing save you need to copy the data (logos, faces, ...) into the save directly. Go to "../data/saved_games/XXX.lg/graphics/" (XXX.lg = name of your save) folder and copy your data into the corresponding folders (team logos into "logo_teams, league logos into "logo_leragues", player pics into "player_pics" and so on).
2. If you want to copy them into one of the Quickstarts (so every new started game has them) you do the same but go to the following folder: "../data/quickstart_games/XXX.quick" (where XXX.quick is either Current.quick, OpeningDay.quick or Historical.quick).
Should you have more questions on the process feel free to ask!
