We can guarantee it will happen with 2.2; it'll happen with any EaW mod since it's a bug inherent to the game engine. We've made some changes which should greatly reduce its occurrence (fewer projectiles is a pretty big deal, AI not attack-looping means fewer battles are necessary in the first place, better fighter staggering), but there's also some stuff which will increase its occurrence (more factions being the big one).
PA stuff will get covered on its own pretty soon, however a lot of it is still things you'll see in other places.
