manhack's following error

[Pooka]

I need some help with the manhacks i added in a custom map, i added:

ai_relationship
ai_follow

and all seems ok with relationship, but the problem is that the manhacks are not going to follow me, they go up in the sky and go more futher... i added some info_node_air, and npc-clips, and it changed noting, can i get some help with that?

(the thing i try to do, its to make my mankacks friendly, and following me, but they dont)
