There is a bug in the map of Chapter Three on the Brutal difficulty level.

When my character reached Chapter Three, the Azak Mire, on the Brutal difficulty level, the game would keep crashing as soon as I entered this map. However, when I played with an alternative character (a 小号，if there's a specific term for it in the game context, you can replace this with the proper one), the game could run smoothly. And the computer configuration I'm using is fully capable of running this game perfectly.
