You are posting in the right place. Too bad you aren't getting any help. Maybe the authors haven't visited the forum in some time? I hope someone with more knowledge of Skaven and data file developing replies soon. Sorry I can't be of more help
However, you wrote you aren't getting into tournaments because AB disqualifies your lists... Sounds pretty weird if AB is the one who is wrong. Can't you just prove your list is correct? As flaws in AB data files are so common it sounds pretty weird that tournament judges trust them blindly :?
