In Vampires Dawn a scripted battle against Abraxas is unwinnable and ends beforehand via event command End Battle
There is a battle in La Leyenda Heroen game intro with a similar problem. It should end via events after some battle cutscene. The battle is long as hell with Player but easy to win however.
