Just checking: you have searched the R:TW modification fora here and over at the TWC?

I am not sure if there is a conflict when you change a faction character into a rebel one. Given EB's complex trait system, this may be the case. I would recommend regenerating him as a rebel character and giving him generic rebel traits. Also, remember that the script needs settlement names in order to calculate financial aid and place reform markers and governments, so you also need to change the script files. I can't help you with the map, I am afraid.
