MY EMPIRE IS ON THE MIDDLE, THE RED BYZANTINE. 
I'm playing the Roman Empire (changed the color to RED from PURPLE), and my gold/florins/stall is SCREWED! 12k is all what remains from a 120k money. I've noticed something on the bottom of the Faction scroll list, the info for the economy. There's a whooping 41,371 Expenditure! Where'd all the money go!? I have 62,774 expenditure for the army, and I'm happy with it, because I have almost 10 stacks of Skoutatoi Spearmen and byzzie light cavalry (can't remember the unit in blue uniform). I KNOW corruption is the main source for this, but, really.... 41k florins only for corruption!? 
Any tips guys? Any ideas?
