Your output in the BPI player is the blueprint reference of the character, right? It is going to get the entire character blueprint, and you end up with a hard reference. I say, just remove that output. Then, in your character blueprint, implement it as an event (from the interfaces tab at the left, by right clicking on it, and clicking on Implement Event). Link your Bind Event to OnObjectiveIDCalled with your CreateEvent there. Delete them from your blueprint on the image.
