I’ve tried playing The Boomsday Project solo puzzles. When entering the puzzle I was currently on
Electra Stormsurge Lethal
A Shaman’s Strength
the puzzle didn’t load.
I restarted the game and now as soon as I enter the game it says “You were reconnected to your last game” and the game freezes.
I also tried logging into Hearthstone on Android phone and something similar happens. The game freezes on the “inn doors” loading screen and the phone displays a message “Hearthstone isn’t responding”.
