I wonder if event transforms don't stop processing once one action is
taken... I seem to recall this from a forum post somewhere in the mists of
time. We'll probably have to wait for a coder/Matt Ray or Chet Luther to
comment, but that seems to be the only codepath that sets the severity and
then tries to do something else... Just idle speculation here.
