One thing I noticed in the new update is that, if your aircraft has more than 2 types of ammo, the modifications menu doesn’t show the ammo belt of the largest caliber.
I’ll show this with 3 screenshots.
The Ju 188 has 3 types of defensive guns: the 8mm, the 13mm and the 20mm. But the ammo belts for the 20mm isn’t shown.
The Finnish Bf 109 G-6 has 13mm MGs and can carry either 20mm or 30mm guns, but it only shows the 20mm ammo belt, even though the 30mm is currently equipped.
The Yak-9UT can carry 4 types of guns, but the ammo belt selection for the 45mm doesn’t appear.
So, have any of you noticed this as well?
