Greetings! I have found that summoned by player werewolves don't attack vampires and predators. And I fixed it. Enjoy it if you play as werewolf against vampires. This mod requires DLC Dawnguard installed and active.
This mod shoud not be compatible with any other mod that changes summoned werewolves. This mod is designed for playing without global gameplay changes. So use it on your own risk with any mod that changes werewolves.
