i didnt make so much army in 2 days....
besides i have on another realm the double army and again imnot paying so much.... sooo something wrong here
Then who did make it? The upkeep you pay is exactly the one you are supposed to pay with this army at home and/or on a mission. The upkeep numbers of each unit can be checked in the barracks. Bear in mind upkeep of traveling army is more expensive.
