Weapons in shuttle bays

Ok, help me out here. I'm seeing a recent spike in offensive and defensive costs in my main. This is a new development. The only weapons I have are in the shuttle storage. I didn't think that they would be doing target practice in shuttle bays. Also strange is that these weapons should be deactivated. I say this because the GM determined that all weapons must be deactivated if in shuttle bays. Glitch?

To prevent players from huge weapon stocks in nations via space centers they are still under the same limitations as if they are in your country.

They do use less ammo and materials though.

But they are still deactivated. I guess what I'm not sure of is, do deactivated weapons still use up ammo?
