Forcing Methuselah to play cards you cannot play

@ANKHA: Would be nice to get an official clarification, because the switch to a totally different target seems too severe in my book to force a play ...

Also compare to this: Announcing a Govern The Unaligned at superior, indicating the only vampire in your uncontrolled region, then realizing he's older. Would you now force that vampire to bleed? I don't think so ...

AFAIR LSJ always ruled for a total rollback.
