Really sucks that I can’t add a photo share link with the screenshots, it’d be much easier to show whats going wrong. But in regards to the bugs my first issue was with a connection issue when entering the lobby for a battleground, with the Illidan Hero floating at the bottom and acting as an non-interactable card and having a weird short delay when displaying the hero information. The other issue happened when it was the final two and my opponent left before the start of the next battle. The battle continued as normal when facing Kel’Thuzad but froze after the battle finished.
Again I have screenshots that I could share through Flickr, to help visualize the problem, but sadly I can’t share them here.
