So whenever I’m about to face a new boss, the card that is flipped over on the deck-view screen always shows Alchemist Wendy as the next boss. It’s Alchemist Wendy, every level… even the friendly encounters are Alchemist Wendy.
Of course, the actual boss that I face is still being chosen randomly, and the friendly encounters work just fine. I just never know what it’s gonna be until after I start the match.
Not exactly game breaking, or anything, but mildly annoying. It started right after I purchased the remaining levels.
In order to save customers the effort of posting bugs that are known already, Blizzard has made a sticky post “Known Issues” that is right at the top of the screen in this forum.
The issue you describe is included in it.
