I don not believe that you can disable the city life from a map on a single building.
Might I suggest that if you have other building in your village, that you make them the building that is tied to the peasant and guards production and leave the "GORAUS" building to only produce the city life aspect.
When you change the troops in the squad, then you must use the size formation that they use in the game. 45 for Calvary, 120 for muskets, etc. I am not sure why your riflemen do not form up. they should. Possibly something in the way you wrote the file.
I would try again, and experiment with other troops, or better yet place your file verbiage here and have one of the modders look at it and give you some advice.
I am afraid that there is no way that I am aware of to create troops from buildings other than in villages. But it is interesting idea, I will try some experiments and get back to you.
