Unwanted hero skin changes
Hello, when I choose a hero skin, it automatically resets or change after each game or when I restart Hearthstone. It’s a little annoying and strange. (In my collection I put skin in the frame, I have already tried to remove all the favorites skin or also try to put only the skin I want in favorite, the problem persist). Anybody got a solution, please? 
Does it happen with specific decks only? Please check also your deck settings (Collection → Click on the deck → Click on the “Skin” arch) & make sure the option selected there is what you want.
In the screenshot below, I only have 1 skin as favourite at this time, and I keep the option checked to make sure I get the one I want. If I uncheck it, the skin will rotate to something else from the pull I own.
