Afaik, it depends.
- If a chapter is reset because you changed something and the pass was refunded, all of these 4 are reset to whatever they were before the reader started the chapter. (ie. by the end of Ep3 the reader has 5 character points, they read Ep4 and now have 7 character points, then you edit Ep4 and they’re refunded a pass, they’re now back to 5 character points).
- If you send the readers backward using a label, like if the MC dies and you make the reader repeat the chapter, all of these 4 are kept.
So, if you want the readers to be able to skip because you tend to edit published episodes, you’ll need a quiz, otherwise they’ll miss all the gains and stuff during the episode.
