Ah, I too have encountered the levy archer bug, makes for an interesting experience

Anyways, since I'm making this post I might as well chip in with some other stuff. Being Norwegian, and a fan of Norwegian history I jumped in, and started a Norway campaign - I'm having a lot of fun, and what comes below is mostly nitpicking. I might come across as negative, but that's merely me trying to be precise about the points - overall I very much enjoy the mod.
My biggest issue is with the two units you'll use the most early game. Drengjar, and Viking Drengjar. Drengjar is norse for youth, and is used in Danish today (Dreng=boy).
However:

They have the same description, and very similar names- a viking youth is apparently quite a lot worse than a normal youth. I think it'd be a lot better if one of the names were switched out, and a different description provided for preferably both. I'm a bit of a history buff, and the mod reflects the overall theme of the Norwegian army at the time being farmers, the so called leiðangr.

Huskarlar is already plural, and thus the Huskarlars in the description is uneccesary
The Veiðimenn are described as being unable to fight an being awful in melee, yet their stats are better than the Viking Drengjar, who are cited as not to be underestimated.
I'm not fluent in all the mechanics of the game and how things are supposed to be, so by all means correct me if I'm wrong. However, upon building an Archery Range one unlocks the Gestir. But if you upgrade the Range to a Marksmans Rage, the option to recruit Gestir is removed, and no new units added - Why is that?
Since we're going all out on historical accuracy, I should mention that there is no evidence or sources of Dragon Boats having ballistas on them (Yes, I know it's the vanilla description, but I thought I'd mention it)
The landeværnmenn are spelled differently in the unit name and description, I'm not quite sure which one you want to go for. Anyways, Landeværn means "land defence". I'll here bring in what I mentioned earlier - the leiðangr. (Leidgang in more modern Norwegian). Leidgang was how the Norwegian army was raised. All farmers had a duty to serve, and that was called Leidgang. Thus, I think it's better if landeværn, although appropriate (but not historically used) could be replaced by leiðangr.

Swede or Swedish
Skjöldborgsmen have a few typos in the description, "Norses" and "ofr" (Norse and for)
Now, I see this comes across as a tad nitpicky, but I thought I'd go all in - If you'd like it, I'd be happy to write some new (better?) descriptions for the Norwegian unit roster. Cheerio!
