I was doing the submarina parts search last night, right after i finished the toxic waste one.
I managed to get the fist few parts, but when i need to get the one that's next to the sunken ship (Elephant or something, there's also the undercarrage of a plane next to it), i can't grab it.
I'm doing them with Micheal, and even when i'm very low to seafloor, even hitting it, it still won't let me grab this part.
It's frustrating as hell! I even ran my boat onto the bank and blew it up. The people in the nearby Fort Zacundo didn't love me for that
But anyway, anyone having the same problem?
