As a UI user the proper option is #6 anyway.
I tried to install the Fogotten countries mod and again...CDT at 60%
(it used to work fine before the AC Installer 3.3)
as soon as I deactivated it, the game works fine again...

I use both, UI and forgotten countries witch AC 3.3
there is no conflict.

wasn't there a twitch to the forgotten countries theat introduces the new rundel markings taht you have to copy a certail "files" folder to MODS??
I was wondering back then but maybe you mixed something up there.
check threads and readme perhaps.
