I recently completed all of the San Fierro missions, and unlocked the Toreno missions. I obviously lost my weapons from completing the mission for Woozie, so I decided to finish the snapshots for the weapon spawns, as I had done some of them months ago. I went to all 50 locations and no icons are visible anymore, but I'm somehow stuck at 48/50. Is there a way to make them respawn, or do I need to restart the game fully? This was naturally my first attempt at a 100% play through. Thank you.
