I've run into the following, highly annoying weapon bugs.
Using Max Charge Micro Fusion Cells in a Gauss Rifle does not increase its damage at all. The damage and dps ratings dislayed in the Pip-boy do change, but the actual damage done by the weapon in combat remains exactly the same.
The same happens with a Gatling Laser modded with Focus Optics and Carbon Fiber Frame: the damage ratings ostensibly improve by 75% as they should, but the actual damage done by the gun in combat remains the exact same.
When you modify a weapon with a Carbon Fiber Frame, decreasing its weight by 50%, the weapon's Strength requirement remains the same! This happens at least with the Sniper Rifle and Gatling Laser.
