Affected:
PROCESSOR_SELECT_FUSION, PROCESSOR_DESTROY_STEP, PROCESSOR_RELEASE_STEP,
PROCESSOR_SENDTO_STEP, PROCESSOR_OPERATION_REPLACE,
PROCESSOR_SPSUMMON_STEP, PROCESSOR_EQUIP, PROCESSOR_SWAP_CONTROL,
PROCESSOR_REMOVE_COUNTER

PROCESSOR_SPSUMMON_STEP_S, PROCESSOR_EQUIP_S, PROCESSOR_SWAP_CONTROL_S,
PROCESSOR_REMOVEOL_S, PROCESSOR_DISCARD_HAND_S
