Just fought in tag arena. Won the match but as it was transitioning to the victory message all the champs disappeared and the game just hung. Didn't freeze, the background banners were still moving, I could access chat and the timer kept counting up but it wouldn't do anything else. 

Pause button disappeared but if i minimized it gave me the skip options but they didn't actually work, just kept hanging. Waited about 5 minutes and had to quit, taking losses on all 3 battles and losing points. 

Fought the team again and the same thing happened, again losing points for all 3 battles having to force quit the game. 

My champs were apothecary, miscreated monster, Madame Serris and Skullcrusher. Other team was tormin, maulie, drexthar and roschcard. 

Seemed like maybe it was an issue with the freeze and hp burn animations
