... I've seen many reports about mod.packs that do not work as "mod" type and you have to make them "movie". Until now I have not any such problem working with factions, units and custom units for my mods. Avoid to make "movie" mod.packs (exceptspecial occasions like _loc files, videos, etc.) because later you might have problem as happened many times in Empire. Movie packs do not need activation through user.script or Mod Manager (if later is updated for Napoleon) and are easy to be forgotten. These remaining "movie" packs can cause conflicts with future mods you are going to use or with vanilla. Conflicts will be responsible for disabling expected elements of a mod or vanilla and sometimes for unexplained CTD's.
