why cant I train billmen?

[Balrog]

I have all the requirements according to the MTW Building and Unit spreadsheet I found from this site but I can not train those units. (i.e. they dont show up in the training screen only the regular units are there.)

I am English

Billmen
I have all of the following built in Mercia: Castle, Town Watch, Spear, Spears WS, Spears Gld

Longbows
I have all of the following built in Wales: Castle, Town Watch, Bow, Bows WS, Bows Gld


what gives?

on a side note I find this quite frustrating there needs to be a better in game way to find out what you are missing to create a desired unit.

Just figured out why. I started the campaign in early time and these are high to late time frame units.

a follow-up question the: does the advent of the compass, then gunpowder denote the change in times from eary to high and then from high to late?

Total elapsed time to answer: 8 minutes. Man we're good

Just kidding Balrog. Glad you sorted that.

I never thought of compass and gunpowder that way (as harbingers of new eras)...but I guess that would be somewhat accurate.
