Yeah, i know about the mods, i've been sniffing around on totalwar center, downloaded the all civilizarions one and even fixed the wardogs my own way since the one wardog mod available doesn't really suit me...
But the bug that got me most pissed off seems to be pretty rare ( i guess it could be crappy pc related) the one where you have a certain group of units selected and when you give them an order, it gets all messed up. Sometimes units that weren't selected get the orders too, sometimes the units that WERE selected refuse to follow your commands etc...
very game breaking if it happens in the middle of a big battle and you don't notice the bug happened immediately after it does, you can get your archers in a melee fight, make your general charge some phalanx, all kinds of fun stuff
