What steps will reproduce the problem?
Happens whenever my Legion class-weapon (eg. Aluneth) whispers to me

What is the expected output? What do you see instead?
no error :)  I believe this should flash the chat frame somehow?

What version of the product are you using?
16.1.0

Do you have an error log of what happened?
