That would be an appalling shame! Especially when there is probably something really simple that's wrong.
This morning I am much less convinced that your ForceGreet package is the problem, and I wonder if some other package is kicking in and making your NPC follow you around.
Would it help if I posted a tiny mod somewhere for you to look at, that just set up an NPC to force greet the player and then attack if they refuse to leave, or take too long to leave?
I've dropped the whole quest to start over last night. I think I was going at it entirely wrong. I went around watching some youtube tuts and the wiki. I understand how the dialog view works a lot better now.
My biggest question right now is whether there is a better way to trigger the bandits to come out. Should I surround the area with a trigger box, like I did before. Or should I use some other method.
Regarding the ForceGreet problem. I think I had more than one instance of it running. There's a dozen places that these little scripts can be placed. I think I had one on the NPC and at lease one in the quest maker. With the NPC continually following the player after the quest was completed made me realize there must be more than one instance of ForceGreet at play.
I would really appreciate an example of how this should work. My next quest for the mod is going to be pretty complex, I think. Involving the player getting knocked out and the screen fades to black and he awakens in a dungeon cell. Then gets knocked out again and awakens at the feet of the bandit leader.
