Even though I removed the list of zombie types they will ignore, the scarecrows that spawn at night do not attack the zombies that I have spawned in from ZombieHorde.  Can someone look at this?  I want basically every type of NPC on my server to be at war with each other but for some reason they do not attack them.  Alternatively, if this is not easy to implement, could you implement a feature where they attack any entity that attacks them?  I am not sure what ZombieHorde uses as their NPC type but I am pretty sure its a heavy scientist.
