The Gear Upgrade Reset Scroll doesn't work.
I came to the conclusion that I added wrong stats to my staff which was already on upgraded level 7. I got the scroll and used it on the staff but it still remained at upgrade level 7. It didn't reset. Today I got a new scroll and tried again, while having my staff equiped, but it didn't reset either.
How do I reset my weapon's upgrade so that I can pick new stats?
