Mods work in editor, but not in game

I Had thought that I saw a post on this before, but it either gone, misplaced, or I am just not typing in the right search curriculum.

My mod’s hand-based (melee) items all work fine, but not the projectile weapons besides the ‘Tranq’ gun (which has a clip, not single-fire bolt-action and actually uses ammo). The others (Mod’ed Pistols with “unlimited ammo”/ammo not used.) have very specific damage types that work quite well in the editor, but fail to function ‘in-game’ entirely.

Edit: Those two pistols work just fine when I use them in-game, but not anyone else. ???
