I'm in a war against Austria. I attacked them because they had 0 manpower left and only 26k troops. However, no matter how many troops I wipe they're still about 20k troops and 0 manpower and keep pouring in... So, are all their troops mercs? But it cannot be. Their income is twice smaller than mine, according to the ledger, and I cannot field 26k mercs including cannons and cavs without being extremely negative on balance sheet. At one point I thought I wiped them all but in about half a year another stack of 22k fresh troops appeared... WTF? I already drained 130k manpower myself and I cannot recover my manpower or hire mercs almost lightning fast. Does the AI cheat with infinite gold to hire mercs? Length of war is also substantial to bankrupt anyone who take too many loans.
