I've been playing this mod without any problems for a little more then a month and last night I found that I could not start any new games because of a sudden error. The error occurs when a new game is loading and consists of 'leaderclass incorrect' and lists the same error for all of the new leaders added in this mod. The game then loads up using only the firaxis civs. I have not modified the Civ4DiplomacyInfos.xml file however I looked at it a moment ago and it is full of broken tags and so on: Can anyone explain how the file managed to scramble itself? How can I fix it so I can play the game again?
