Just run into a bug.
Ordered directly my watch officer to man the Flak, but strangely the Flak was moving without the guy...
I had the little icon top right though.
2 swordfish attacked me, and the Flak was ineffective !
Not to say the result...
I had the correct flak icons enabled for fire frei and attack all aircrafts.
Also from some time now, when i can see the Flak man, he is standing crouched with the gun aiming vertically
even with no contacts.
It’s a new sub VIIB, with stock Flak (not the twin) at the rear of conning tower.
