My sniper gun is not shooting in the mission Save Oliver.I also noticed that when i was escaping with daisy in the vehicle i was supposed to shoot but my gun didnt work. It will be great if i can find a solution.
After you save daisy and go int the jeep you should shoot the others who come to attack you.But I wasnt able to but i somehow survived that. And after I burned the drug crops I went to that nearby village and tried the mount gun. It didnt work.Also the guns of the vehicles didnt work. I guess that the guns that show the infifnite sign on the place of ammo doesnt work.
