Omen of Whittling Bug ( consumed currency no effect)

When I used the omen of whittling in my inventory and I clicked the perfect chaos orbit highlighted all three prefixes on my ring. But when I used the perfect chaos orb, it consumed the omen of whittling and the perfect chaos orb, and all 3 prefixes stayed exactly the same, none of them changed at all. The values didn't change the tiers didn't change nothing.

Chaos Orb rerolls one of the modifiers on an item (with whittling lowest tier) and the rerolled modifier can be the same modifier of any tier. I guess in your case when you rerolled your item the modifier that got rerolled by the chaos orb became the same modifier and the roll ranges also stayd the same. Just unlucky coincident.

I have had many times this happen to me when you chaos spam an item and try to find the modifier you want.
