@Skibir - I encourage you to update to V 1.1 where that issue has been resolved.
@altilagi - There is no "total war" sub-sub-submod set up for Heirs of Elendil. Maybe that is something we will do for the next version.
@Kindjal83 - After you get the Shards of Narsil at Imladris, Aragorn's quest is "over" in the sense that now he has rejoined with the rest of the faction to unite Arnor. But you can still get the Oathbreakers at Edoras at any time after this.
