The last hotfix broke capacity perks tier 2 rank 3, and tier 3 rank 3 for Torvald. None of them increases any capacity now.
Hey Fritte, we just checked and verified that the capacity perks were broken earlier due to an outage, but are indeed working now.
The perk rounds down the amount of ammo it increases, so for mortars, you won’t see an increase in number unless you have at least a 20% capacity increase.
I hope this helps!
