I think what happened was I started the first store hacking mission for Kinzie and was having trouble dealing with the cops afterwards, so I quit the mission to take off the heat because there was no golden CID to destroy. Got my Merica gun and the mission started completely over, but it gave me puzzle #2. When I got to the last store, it gave me puzzle #1 again, the straight line across. Nothing major, but a little glitch nevertheless.
