How to make NPCs stop combat?

[Starcrusher]

I could use some help setting up Shang Village. The Imperial Soldiers and Shang Villagers are supposed to be fighting each other in small groups constantly. I have been able to get a group to do that, but I have two issues. First, when they fight, most of the time it looks like only one side is hitting the other i.e. the Imperial soldier shows to be whacking on the Shang villager, but the villager doesn't appear to be fighting back or vice versa. The second issue is that once the soldier kills the villager he doesn't drop out of combat mode and I don't see a LUA function or a way to make him stop combat. Any help you can provide would be appreciated since I have spent many hours working on this one small area. I almost have it finished, but I want to get this going like it was on live.
