I decided to make some changes in my game (VI, patched) and found difficulties I can't solve myself. I need help of advanced mod-makers.

1. Is there any way to create new GA goals?

2. How to specify how many percents of different confessions must be in a province at startup?

3. I'd like plague (and other illnesses) to decrease the number of troops in a province. It must act like crusade passing through catholic land. Is it possible to cause that crusade'a action when epidemic happens?
