Refits - Torps + Fuel, but no Gun Ammo?

[Schlageter-JG26]

I noticed that when I pulled into Midway on return to Pearl to top off the bunker I came away with my replacement torpedo slots refilled (tubes themselves remained in their prior state of loaded or empty). I got my bunkers filled and all these shiny torps...


... but they couldn't give me more GUN AMMO? Yeah, they can spend a virtual day putting 20-foot tubes into the sub 1 inch at a time, but no one can run some shells and magazines across from the dock? Didn't seem to make sense to me. Likewise, the refit did not take any time in the game.

Don't get me wrong, gas and torps are GREAT. Esp with my main torpedo crew having the "Increase Torp Speed" quality! But the deck gun ammo is JUST as important to my survival.
