Comment (by JouMxyzptlk):

 That is a pretty annoying and unexpected bug to skip chapters
 unexpectedly.
 Especially when the console tells me that the chapters are all detected.
 Now I a forced to check my older encodings which were a wasted time.
 Who introduces such stupidness in the code as default behaviour?
