I don't know if this is a content pack glitch or flans mod glitch, but any vehicles that have a .30 Cal or .50 Cal gun mounted on it ( and this includes the humvee from Task Force's content pack, humvee from the Modern Warfare content pack, and any vehicle with said gun on Manus's Modern Warfare Content pack) don't fire rounds. I have tried each alone with their dependency packs, in which the gun still doesn't work. The right ammo is in the vehicle, yet when I shoot the sound does come on, but no projectiles are fired from it. I have tried the latest 1.7.10 forge and recommended 1.7.10 forge, and even the previous 1.7.10 version before that. I have tried both Flans mod and Flans+ mod. I am using the correct versions of packs for the forge and flans mod I am using (1.7.10). I am using required dependency packs that have been stated by the authors of the content packs (simple parts and smp parts).
