As you can see, I reforged a piece of equipment, but when I return to the hero, it doesn't update. I had to unequip and then find the reforged gear to equip it again. I should add that this doesn't duplicate the item or anything. In the screenshot, you can see I have level 85 gear, but the description says level 90 because I had already reforged it — and that’s exactly the bug.

It also gets fixed when you leave the hero section or switch to another hero and then go back to the one you were equipping, so it doesn't affect gameplay at all. I'm just reporting it just in case.
