PvP (3 on 1 Game Freeze)

Sorry in advance if this should be in a separate forum.I was playing PvP last night, stone league. I came across an opponent that only had one bird(knight), and very low level. This is the 2nd time I have seen this type of battle so I knew in order to get 3 stars I had to kill the opponents bird a few times. I used Paladin, Mage, and Rogues, I used Paladin to kill, then used the support functions of the others on each bird, until all 3 basically had each others support functions. When his/her Knight came too, and attacked he immediately died, causing the game to freeze.I could still tap each bird to see their details, the game just never progressed to my turn. I have a screen shot, but do not know how to upload. Anyone run into this?
