Hey guys, about "all hidden weapons" category. I know the rules is "Get all weapons scattered around the map." I made that run and I toke only all hidden weapons including the safehouse's baseball bats. But I still have a doubt: I have to take the molotov near to a package that is in black tunnel between 8ball shop and harbor also (though this weapon don't be fixed as the others)?

Could someone explain me the specific weapons I have to take in that category? I am confused.
