bug(I can't reproduce it though):
i just started the game as male ninja and bought some units at first village and then went to 2-star village and then saved. tried to conquer village right away but lost so i loaded up the manual save. for some reason, I was able to buy troops from the 2-star village and it shows as green text on the world map.
"What the-? Enemy himself has come to our gates" No shit. How do you think did I conquer your other "towns"? You think I just sat on my ass and waited for them to attack me until they had no army anymore?
@coldfusion2142, then it would obviously be multiplicative because in no way did the devs waste time on an ancient just so it will be bought and upgraded once.
