I agree that rx_dropped is not the correct stat to bump here, but
I'm totally against the event disappearing completely into thin

You have to replace the rx_dropped bump with _something_.

The only reason this hasn't been "fixed" yet is that everyone is
too damn lazy to implement that "something".
