Here is the scenario:
I have a Komainu on Archives and a Chum in the second layer of ice. Runner plays Parasite on Komainu. Runs and does not break Chum's sub. Continues run and kills Komainu with Datasucker. Chum falls to the first layer and runner encounters it again.
On jinteki.net how it played out was the runner used one datasucker token to kill Komainu (killed it before Chum could give it +2 strength) and now the first Chum sub applies to itself when the runner encounters it again. Runner had 2 cards in hand and flatined. Seem kosher or did jinteki.net bug out on this one?
