Script for NPC vs NPC but ignores player aggro. Need help

[kayen85]

For an event I scripted I have an NPC mob spawn and then attack another NPC close by. I wanted to set it up so that the players needed to kill the attacking NPC before it got to its target, but the NPC will ignore any player damage and continue to attack its target.

I tried setting the attacking NPC to non aggro, but then it refuses to attack its target through the script, so that didn't work.

I am thinking I may be missing something obvious here on how to accomplish this.

Any suggestions would be appreciated.
