PVP Fight that was bugged

What you were expecting to happen, and what actually happened?

I expected to do a PVP fight against tweetie1571, instead the game froze.

What are the steps to make it happen again?

It said that they had about 900 power and showed a picture of a knight, so I thought no need to scout, easy win. Instead the game loaded with no opponent at all, and the game froze, the only way for me to close the game was to control-alt-delete.

Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
This screenshot here is of that battle:
