In warhammer 3 you can scout with heroes, all heroes can detect an ambushed enemy, is this the case with Shogun 2?

I discovered this problem when I was playing the game. Hope the staff can fix this bug as soon as possible

because they are close to kyoto? well i tried like 100 turns TWICE. this game has a problem with money. i can control 10 different cities, have all the necessery building upgrades that suppose to boost income and food and it dosent matter, i'm still bankrupted over and over despite i have it all, despite i resarched everything, had upgrades. and so. and the enemy? it seems they have infinite money, because they spawn so many huge armies and they even do it from the very begining, so something here is very ...

What should I choose in order to get the "hero of the shogunate" achievement ? Long or short campain is enough ?

Let me Know
