[TEC] Type XXI Deckgun (Almost there!)

[York2016]

Hi all,
I've been trying to add Deck Gun(s) to the Type XXI U-boat and I believe that i'm very close to getting it working.

The Deck Guns do appear in-game on Deck(in quick mission) however the crew management screen does not show the Deck gun compartment(only the "box" which the compartment is supposed to appear in) nor the Crew slots to man it. The "requisitions" screen(where you get new equipment and torps for your Sub) in the Captain's Office in the Career mode does not show the Deck Gun either(Only "Light Flak" as usual)

So, they're just huge metal fish right now. I've been able to make it so that the log doesnt say "Deck Gun has been destroyed" ten thousand times(forgot to put 64=24 in the Type XXI's list of compartments) but can anyone help me in adding the Deck Gun crew slots?

I am using LSH 2015.

List of files which i have modified to get this working:
NSS_Uboat21 .sim, .cam, .dat, .eqp
basic.cfg
conning_barracks_15.cfg (Type XXI Conning Tower)

Any help would be appreciated
