Ignore the previous post, i just loaded up the old LOTR_EN 1.5 and the Arnor list seems to work there.
Probably something one of our club members did that stops it from working properly in our modified version.
Sorry to have troubled you all
I remember we were trying to fix something in the Arnor list at one point because you could not select the banner option for the Warrior of Arnor.
Obviously what ever we did to fix that part broke the archer count in the version we modified.
Oh well, back to the drawing board hehe.
