The mystery solved for hunting Stalker for blueprints. Assassinate Ruk (or any non corpus boss but Ruk has best drop rate for Orokin Cells) first. Play two nightmare missions. Kill Stalker within those two missions. If no stalker, assassinate Ruk and play two more nightmare missions. Rinse and repeat.
