Blueprint interface not working?

Hi, i am having an issue where an event from the interface event in “Character_Blueprint” is not triggering from the message in “Add Ship”. I have used break-points to determine that the blueprint message is activated when a “destroyer” is spawned , however nothing else happens.

This first image is off the class “Add ship” which is a button in game. it has nothing in its parent class


This is the mentioned blueprint interface.


This is in the “Character_Blueprint” class which is a parent to the class “Destroyer”

please describe your problem in more detail and make clear to which classes these blueprints belong.
