When I buy special vehicles (military vehicles) I get the message that they have been delivered, but they are not in my garage or my hanger. I bought the military humvee (don't know the name) but when I press right on the D-pad nothing pops when I'm in the garage. I bought the tank, but it did not show up in my hanger. But when I bought the attack helicopter it showed up on my helipad. Anyone understand this madness?
