Cast to controller from anim BP replication

Hey I am having a replication problem with my characters anim BP. I am trying to replicate upper body rotation and have been having difficulties with replication for clients I believe the problem may be in how I am Casting to the controller as when character A jumps the falling animation plays for character A but not for character B, this only happens when the cast to controller node is hooked up in the animation BP.

I have included pics of the blueprint setup as well as thee falling animation fail and am wondering if anyone by chance knows where I have gone wrong any help would be greatly appreciated thank you :slight_smile:
