Same here, have been primarily searching on a mulitplay.com server. Driving around the 4x4 for hours and no sighting of Olga (including parts), .308 or Tundra. I kept second guessing if the server was even on 1.02 but the inventory is updated so that's not it...
Even went so far as to install server files on my system and checking the different economy XML files. Found the Olga set as " <nominal>0</nominal> " which I believe is no spawns...?
