I was wondering how animBP work and if they operate differently in a multiplayer/online setting. It is my understanding that each client has an instance of all the animBPs running seperately. This seems to have consequences in the way that I normally implement melee characters who had anim notifys, collisions and animBP working with the collision of their animations. In the game I am working on the client’s melee animations are not working on the listen server, although the listen servers animations are working on the client. 
I’m going to get rid of as much logic as possible from the animBP tomorrow in order to try to get this working. If there is any special information about animBP please let me know.
