Thank you, Mike. So it appears that there is no unit or fiefdom list, that is up to date.
The 'MOS Fiefdoms' file, that you mentioned, is both useful and confusing (or even useless in some cases). For instance, during my Silvan Elves playthrough I've managed to get only half of listed fiefdoms. Certain settlements were absent, one failed to trigger ancillary, and other had different names. I assume that MOS 1.7 uses the Extended map, not the vanilla one? Both the lists are often wrong anyway.
In my current playthrought, with Rohan, the differences vs. 'MOS Fiefdoms.docx' are actually quite minor (yet still present):
1) Only 4 out of the 5 starting fiefdoms seem present. I don't know if the capital (Edoras) counts as Rhovanion / Tirith Thoron? Shouldn't this Tirith Thoron be located somewhere to the East? I have no idea.
2) Only 2 out of the 5 obtainable fiefdoms are unchanged (Isen and Dunlandand). North Enedwaith uses the MOS Vanilla settlement so it's easy to find too. However, South Enedwaith is tied to settlement named Alcfud, and Dor Rhunen to Dor Naurhach. You have to guess which settlement triggers the ancillary in order to dind it.
All in all, Rohan is still quite straightforward. The other factions were way trickier.
BTW. I've noticed, that you are one of the good people behind the Reunited Kingdom sub-submod I was going to play Eriador or Gondor, but I've red that a MOS 1.7 compatible vesion of RK may be comming out in the upcomming months. The stuff looks glorious. Can't wait!
