Why aren't my Sequence Events firing on Additional Receivers?

I have a sequence set up that has an event track that fires an event called Asplode:

I have another blueprint in the level added to the sequence’s Additional Event Receivers array:

I have a Custom Event named “Asplode” in that blueprint:

The sequence plays fine, but when I set a breakpoint, I never actually see the Asplode event fire on my blueprint. Am I missing something?

I’m using this, all working fine
