Hi,

 

I've just defeated all foes with my last standing summoned creature. All of my heroes are unconscious, but they can not recover, because battle is somehow still pending. I think that I should either lose or my heroes should wake up in such a situation. Unfortunatelly, I can not save the game to show the problem, because battle is still pending...

 

That's an odd turn of events. Have you tried getting the summoned creature killed elsewhere?

The fight can't end because there is another enemy engaged, but offscreen. If you can't get to them, then you're stuck.

 

This has happened to me a few times.
