I'd like to add i've had the same problem with a certain enemy in a certain cave that causes a cutscene halfway in the fight when he gets to about half health.
I've noticed that if you skip this cutscene too fast (spamming space) you sometimes go back to combat while the screen stays black. you can actually input commands and the battle continues but since you can't see anything i usually force close the game.
I never reported this bug ingame since it doesn't cause a direct crash so you never get the crash input screen.
