Yes, I also think cache friendly elements is a good idea.

Even though it doesn't seem to be helping much I thought I add a little more detail regarding the Classical Warfare AEA project. Another thing that separates it a little from the base game is more diversity within units.   For example, there were at least 3 common types of bows from 500 BCE to 0/100 CE.  You had the simple bow.  Cheaper, easier to make, but not as strong/accurate as (Composite/Longbows.)  Most of the Greeks were not known for their archery, the mainly used the simple bow.  Then there is the composite bow, almost twice the range as the simple bow, popular among the Steppe people, used by the Achaemenid Empire (Persians) Sele and Ptoles. Then you had the more powerful, bigger long bows of the Maurya and Kushites.  These bows often matched the range or exceeded that of the composite bow. But do it its size had a slower rate of fire and was not ideal for very mobile units.  There were also different types of ammunition used with slings, most commonly stone or lead when available.  Again trained slingers with lead ammunition could often out shoot archers as far as distance.  The Balearic and Rhodians in particular were highly sought after for their slinging skills. Please correct me if I'm wrong   But yes we are trying to make an effort to represent some of the important differences from the time period which made certain archers better than others, while some infantry stronger than others etc.  

If it helps, I tried to run this savegame on the windows side of my computer, and it crashed just the same.

In the Proto-Mapuche and Pampean Peoples mod, we have champion slingers. 

They aren’t champs in CWA, but they are elite mercenaries. They have special stats, were highly regarded in the ancient world for their sling capabilities. Similar with Rhoadian. part of the problem is what exactly are champs?
