I think ive found the bug in your code that prevents people (myself included) to advance during chapter 6 but im not sure.
I believe its around line 27413 in the source code (chp_6_9) .

When you get to the "your return to your room is marred" (chp_6_9) part in the story, there is no "next" button but im not sure if there was supposed one.
I believe there was a missing "</tw-passagedata>" at the corresponding code part because, when I added the missing :
"</tw-passagedata>" right after:
" [[You will visit Lena first, hoping to get some answers.|chp6_10][$chp6_lenatalk to true]] "
in the code, the options
" You decide to return to your room. " and
" You will visit Lena first, hoping to get some answers. "
appeared in the game and enabled me to continue but, there was still no "next" button so im assuming there wasnt meant to be one.
Honestly, my experience in coding is negligable so I dont quite understand what I did but, all I know is that I was able to continue after changing:
" [[You will visit Lena first, hoping to get some answers.|chp6_10][$chp6_lenatalk to true]] "
to
" [[You will visit Lena first, hoping to get some answers.|chp6_10][$chp6_lenatalk to true]]</tw-passagedata> ".
Yup, you're right that there isn't meant to be a next button. One of those options should have appeared regardless of your choices and others haven't had the same issue. I think it's only a few that are having the same issue as you where you can't continue forward so I'll have to restructure the code by the next update if it's an issue for others too. Thank you for sharing!
