According to the guide I'm following, "Parent NPC" needs to be "MyActor", and "Child NPC" needs to be "Player".
If I set Parent NPC to MyActor, Player is not available in the Child NPC list. If I set Child NPC to Player, then MyActor is not available in the Parent NPC list!
What is causing this? I've made a handful of NPCs and never had this problem before.
