Hi Wolfiez! I found a new Iron Fist achievement bug. I have not completed the "Toothless" achievement (progress at 6/14). When patch 2.16 went live, I was automatically given completion credit for the new Defender achievement "Accomplished Iron Fist." But when I expand that, it shows "toothless" as unchecked. Now I cannot get any further progress on Toothless; I've defeated Sabretooth twice and the count does not advance. These may be coincidental items, but it's the only condition that I can identify.
I'm forum-averse, so I hope you don't mind my reporting it directly. Thank you!
