Then I get th=e objective to blow up the tank yet I cant because I already did and that time I clearly saw the tank go up in flames and explode. I reloaded a previous save and tried blowing up the tank before I got to the part of the mission where it blows up the fuel truck, yet when i got the fuel truck the tank somehow was still there and blew up the truck. I've used a satchel and claymore charge and fired my two rpg rockets at it yet it doesn't blow up despite direct hits.
Then my new 'objective' is to blow up the tank yet that is impossible. After the truck blows up, instead of getting a mission failed the game freaking SAVES. Had enough of this mission, whenever I'm driving away with the full fuel truck from the CSAT compound, it gets blown up by a tank.
