is back where it was. I had finished MZ long ago and want to return to play Mothership Zeta Crew mod. Or... I will have to play MZ again... which I really don't want to, because... you know, because it's Mothership Zeta. I tried googling "alien homing beacon" placeatme but the only result was Paulson's page at the wiki. Other searches turn up skyrim placeatme. ufo with the alien
