Hey, I had a problem pasting a password into the password field when trying to make a purchase. Nothing got pasted, but Hearthstone hung up and started beachballing. I had to force quit Hearthstone in order to unblock it. Once I did restart, I was sent to an "unlock your account" webpage with the explanation that I had tried entering my password too many times. However, my account wasn't locked. It was odd, but I circumvented the issue by typing my password into the field manually (which was... fun because I use a password manager for unique 20-character passwords).
