Chapter 4: Progress Block/Bug

[KΛЯMΛ]

When you are in chapter 4, at the treacherous path, if you are down in the trench you can go south, and you get back, to the previous level. But if you go back to the treacherous path you are trapped, and you can't progress in the game any more, you can only fix the bug if you go back to a previous save game or restart the chapter.
