where does the submarine spawn?
The submarine now spawns in the Los Santos Marina (just to the north of the helipad) regardless of the in-game time between 8am and 12am (midnight). I've checked this out in multiple sessions and it's always usually there between those times. NB: As with other submarine spawn locations, it may not appear the first time you arrive in the area. If it doesn't appear for you the first time, just leave the area and then return and it should spawn. Dalamo, Biohazard Abyss and Killzone3265 like this.
