Is it normal, that trying to upgrade really wants you to spend 30+ silver ingots, for just 1 armor piece, or is that a bug? I for instance, I upgraded a sacrament mesh Torso Armor from tier 3/0 to 3/1 to 3/2, which at total costed me 20 silver ingots, and now it wants me to pay another 10 silver ingots. Unlike other upgrades, that go back to previous tier upgrade material requirements, that go up the higher the level it is.
Left one is before upgrade. Right one is after upgrade. Exact same painful requirements.
Please tell me this is a bug, lol.
