I was using my Karta for about 3 games, when suddenly the Level 10 Superbolt gets lodged hard inside the Karta body. After I got home, and had to pound it out with a screw driver and a hammer, it was jammed in so hard. I've since tried the Karta on a few other set-ups with a few other bolts, and the same thing happens with all of them, so it's not the bolt. What would cause my Karta body to suddenly get a smaller orifice?
