Sorry I don’t have a log or save game…
Was clearing out a graveyard of zombies when I encountered a no-win situation.
After killing a zombie, it didn’t turn back into a corpse. Instead, it remained standing but I could no longer target it. It continued to attack my brothers, but I could not attack back. When I moused over the enemy, a blank box appeared. It also was contributing to the enemy count and so I concluded there would be no way to win the battle and retreated.
