So when I play AOS I keep my resource monitor open on a second monitor just to see how much ram and cpu the game is using.  Well there seems to be a strange bug.  I had three armies and when you put them in certain spots on the map the cpu usage dropped on two cores making the overall cpu usage about 47% and the game slowed to a crawl.  You move them somewhere else and it started using 85% all cores and the game was fine.  It wasn't a situation where if you put all the units together the system couldn't handle it.  I actually did that and it was fine.  The problem occurs when you arrange them in a certain manner on the map I was playing.  I have an AMD 6 core.  On two places on the map if I arranged them 3 abreast equidistant apart my cpu usage would drop and the game would get slow. Anyone else have this?
