Storm the Sheep: Crash during opening cutscene right when it's supposed to show the sheep. I believe this is an old problem I've reported years ago. Restarting the game allows me to watch the cutscene without issue, you may need to reach here during a long game session to experience it.

The halls of the God King: After resuming my game from the first crash, the game crashed again during the ending cinematic (after completing the missing on normal difficulty). Re-opening the game and choosing the level resulted in the game showing the ending cinematic again but without the crash.

Final battle (not New Game Plus): game crashed during cutscene when your party thanks the dragon.
