Thought I'd add this issue so it could be updated eventually. The on Notify actor node only has access to the first Gameplay tag in the container. either it should have access to the entire container (preferably in my view, more tags is better) or if this is not possible, then the input to the flow node should be changed to just a gameplay tag for consistency.
Thanks, not urgent i just wanted to record the error, I may eventually get to changing this myself if I get around to it.
