I just got around to trying the new skins. I wanted to use them it on the IXB. I changed the hull name fron NSSUboat9c to NSSUboat9b. I changed the name from Turm9c to Turm9b, too. However, when I went to the museum to check it out, the conning tower didn't have the skin. I then changed it back to Turm9c and went back to the museum. It showed up for the IXC. How do I make it show up for the IXB?
