"Destruction of servers" section:
"If a server ceases
to exist during a run, then the run ends after any currently
open paid ability windows close."
(Newly added bit in italics)
This seems to change the previous ruling on Self-Destruct (which was that the run was already over when the trace happened since everything had been trashed, so for instance the RSVP effect would have expired).
Does this turn on more Marcus Batty kills? On approach to a damaging ICE, rez MB and use him to fire RSVP, Runner spending no credits takes the damage from the encountered ICE, then for the coup de grace you blow up the server to kill them with a trace that they can't pay into!
