If you erase you memory for SAM AF, are you able to start the AF Head quest and get just that? The Weapon, Feet and Head are all the same NPC starter, so are you able to get the AF head c/s or quest before finishing the weapon and feet again?
It would be really annoying to have to wait 3 JP midnights from Weapon, Feet, and Head instead of just the 1 from the AF Head quest.
