Install Trapdoor only on R&D or HQ
(S) Runner is now encountering the outermost piece of rezzed
ice
on a subsidiary data fort of your cho
ice
, instead of passing Trapdoor. The run is now considered to be a run on that data fort. If there is no rezzed
ice
on that fort, Runner is considered to have passed the last piece of
ice
on that fort. Runner automatically breaks this subroutine if there are no subsidiary data forts.
