I was tempering a non-masterworked piece of armor (just received) and was given a “Resource Cost Reduction [8.0-10.0]%” with a 7.9% role. You always kind of feel that tempering is working against you…this substantiates it a bit…just a joke…but I think this bug is pretty obvious.
I do have a snapshot of it if you would like it. Unfortunately, I don’t see an obvious way to do that here.
