Chaotic Expedition glitch

Hi, is there something I can do to stop the freezing of Chaotic Expedition? I've tried auto-attack and changed to single click attack thinking it may not be loading the next opponent before trying to attack, but it continues to freeze. I've gotten through less than 50 opponents and I've had to refresh at least 14 times.

The pic is what my screen stays at. That's after 2 minutes

TIA
