It just happened, so date/time stamp is about 1 minute earliuer than the date/time stamp of this post. The game froze when I got the final succesful hit on the final opponent. Doesn't appear to be coming back, so I guess I will have to resign battle (if it will let me). I can still right click on terrain to see its properties, right-click on cards and actors etc, but the game has stopped in the process of trying to remove the last opponent and give me the victory screen.
NB, Resign battle didn't work, neither did refreshing the page. I'll need to close the browser session.
