Pirate AT-ST Coliseum

When batteling the Pirate AT-ST, I take my turns attacking. Once I take my turns, the AT-ST never attacks. I've left the game open for upwards of 10 minutes, and nothing ever happens. 

I can retreat out of the battle and participate in all other game modes, so I know the game is not frozen. 

Just wanted to bring this up sot hat you all could research and correct this issue.
