So, I've attempted to create some "rocket Artillery", however, when i change the vehicles weapon type, it does not show any of that weapon type in the customization menu, and only shows Cannons, but you cant put those on of course due to the slots being set for Missile Launchers. The weapon type is set to "3" as the missile launchers should be, unless they're not meant to be. don't worry about creating a weapon for this vehicle, i'm sure i can do that.
Issue fixed, turns out i closed off weapons right after Machine Guns, un-including missiles and arty cannons, lol
