Not sure if I did something funky with my interfaces, but they all are expecting a target to an interface now. When left for target (self) they fail to actually call their event.
However, if you cast the object from itself, it finally works. I experienced this while running through the tutorial made by Unreal Engine for a basic inventory for UMG. Both of the interface calls created in this tutorial continue to fail until I cast them to the actual interface, even though a target of self should suffice. Is anyone else experiencing this?
