These changes looked a lot like I wanted to change and had been so I tried them.
Two issues with it and the warband version.
1 - Capture for elves just doesn't work. The troop editor has them as capture but they still don't show up after a battle.
2 - incorrect mesh prefix for meta meash copy: L and incorrect mesh prefix for meta meash copy: R errors in some fights. It doesn't stop the fight, it knocks you out until you hit ok, multiple times.
