Firstly thanks for all kind words.
@KK
I so wish what you posted on the screenie was a planned AI strategy... normally AI uses certain formation to deploy behind gate, in case of Dol Guldur there isn't enough space to set up proper formation, so AI puts non-fitting units wherever closest it can.
New AI handles gate defences a better than previous ones though.

Probably it's installation issue, verify it by pressing "C" on campaign map, mission and achievement scrolls should pop up.
@brymht
Other mods rather don't mess with battle AI files, although there's AI section in campaign_script.txt - and most mods alter it. AI might be heavily influenced if its section is removed from campaign_script.txt
You'd need to manually check EDU if all units that have "elephant_crew" are put in horde formation.
Then copy contents of
this file and overwrite campaign_script.txt section that starts with "Germanicu5".
Then copy all AI files and folders from the latest AI .zip file, apart from "world" folder and its contents, to a directory of any mod you installed.
This way AI will be made compatible with it.
