Join Up (solved) Now Map problems

[Jon]

How and where do I change who joins up after an event/battle. I have in a patch that it skips from Orbonne fight to the beginning of Ch.2 Orbonne, but I don't want Rad, Lavian and Alicia to join up, I want them to always be in my party. How do I do this? Also, how can I change it so that those three are always controlled by the AI like Gafgarion and Agrias? Any help is greatly appreciated.

Edit: I figured out how to get Rad, Lavian and Alicia from joining, but when I skip the entire first chapter (so Orbonne to Orbonne chapter2), it goes to the world map and there is a line going to where Dorter would be but I can't move. What did I do wrong this time??
