I jumped from 2nd to 4th Quest

[Odanaki]

I'm actually playing with version 2.50 Build 31 (2.53 Beta 10). I just wanted to go back to the original. So I played 1rst Quest and 2nd Quest. At the end of 2nd Quest, the game jumped to 4th. How can I go back to 3rd Quest?
:spin:

Start a new save and enter the name "ALPHA" no quotes. This will start you off on the 3rd quest (The 3rd is actually my favorite of the 5). :)

If you beat the 3rd quest with 0-deaths you will skip to the fifth (4th is too easy for players that can beat the 3rd easily), however I don't remember anything about skipping the 3rd quest so it might be a bug

No, that's right. You skip to the fourth quest if you finish the second with 16 hearts.
