Well there is Awakening of the Rebellion. It is a very great mod with tons of changes and imho it is the best atmospheric wise. There are lots of story elements that actually might lead to a Battle of Endor, when the Empire manages to build the 2nd death star. Sadly, it is a bit boring to play as the Empire, as the AI is unable to make meaningful use of the Rebel forces (i.e., it cannot use fighters and infiltrators efficiently).
Did you at any point install RAW?
IIRC i is this mod which changes the default AI-behaviour for raids and similar. For any reason and that is true for all mods (till now) that the mods/AI folder is for any reason not really working.
Sorry link not with me in the moment, but I did see a post in a forum that one modder team has found something. To really get the AI modded working you have to put AI folder in the root folder.
As usual the dislaimer right away ;)
DO not forget to make a backup :D
