my progress on all the four wings is the same, 100% with Mage, Shaman, and Hunter, and Lesser Heal & Shadow for Priest; which I think was my exact progress on Chapter 1 before the patch. It looks like that got copied over to all the chapters, and led to me losing some progress (e.g. I had finished Chapter 4 with Warrior at almost 100%, but now have nothing there) while gaining other.
Widely reported. Have experienced it myself as well.
There is a visual issue with Chapter 2 – 5 showing the crowns for heroes that have beaten chapter 1 instead of the actual progress for chapters 2-5.
The Hero Power and Deck selection checkmarks will show the chapter 1 versions instead of the correct chapter 2 – 5 versions. This is a visual issue.
