Yea i've had that happen in this case that trick didn't work. It just froze and wouldn't move to the next combatant.
When summoned creatures get killed during someone else's turn the game will sometimes jump to the wrong combatant, and you will see the message "Not [charname]'s turn". You simply need to select the correct combatant by clicking on their portrait. At least this is what has happened in my game from time to time.
