Equipping multiple armor pieces with a carry more heavy ammo perk does not change the maximum capacity of heavy ammo my character can carry beyond the first increase. For instance if I equip the Armamentarium (chest armor fully upgraded with Carry more Heavy Ammo perk) my rocket launcher and my machine gun ammo capacity increases from 4 to 6 rockets and 150 to 300 bullets respectively after using a heavy ammo synthesis. However, if I then equip a second piece of armor with the same perk such as the Kellslayer's Greaves (fully upgraded with more Heavy Ammo perk) or the Willbreaker's Greaves (fully upgraded with more Heavy Ammo perk), and then use another heavy ammo synthesis, my maximum heavy ammo does not increase beyond 6 rockets or 300 bullets. The perks are not stacking, even though the help section clearly states that each perk should add 1 additional unit of ammo capacity, 1 rocket or 100 bullets. Please fix this bug.
