Rome: Total War Easter Egg - Hidden Father Ted Reference

You'll need to find the file export_descr_traits.txt file located in the \data subdirectory where the game is installed, and it lists the traits that can be earned by your family members in-game.
A series of these entries are titled "Drink" "Arse" "Feck" & "Girls" - an obvious reference to the disgusting priest Father Jack in the TV series Father Ted.
