Didn't work. I think the change you did is just for the "satisified everyone" trophy from what I can tell looking at the difference and surrounding code.
Well, I may still have some good news for when you wake up.
I figured out what was causing the original issue and corrected it. I just tested it on a copy of the official English version, loaded a save where I didn't have her on the list, and there she was, just like in the Japanese version. The one caveat is that it is tied to entering the Clubhouse Village (since the flags are supposed to go up when you first re-enter it after completing the Expansion). It'll also work automatically if you load a save there, but if you're post-True Ending and stuck in the basement, it won't fire. I've included a workaround in that case, but I can't vouch for its efficacy quite as well. So use it only as a last resort.
As with the previous attempt, you just need to overwrite the file that's currently in the game, Map008.json. Simply take the file out of the .zip and copy/overwrite it into the game's www/data folder. You can find the workaround in the "USE ONLY IF NECESSARY" folder, same thing, just copy/overwrite Map063 from that into the www/data folder.
This has actually given me an idea or two regarding the NG+ crash. I'm, again, no expert in code, but I have an idea I might be able to try. However, I don't have any saves where I've been able to reproduce it.
UPDATE: I was able to get a save that can reproduce it, and I've narrowed it down to a specific part of the code (it's the part where the game tries to put your progress data from right before you entered the memory room back into place as you exit it), but it's pretty confusing. I can take out the part that breaks it, or perhaps make it so that the game doesn't "hold" data when you enter it after finishing the true ending, but who knows what chain reaction that could cause, so I'm looking to see if I can decipher what
specifically breaks it. I've also confirmed that a save made with the English game breaks in both the English and Japanese versions, but I don't have a Japanese save that can trigger the issue right at the moment, either, so I still don't know if this was an issue caused by the translation or if it was always in the game. Determining that may also determine how to fix it/if it's even something I can manage, so I may have to speedrun the JPN version if/when I have time.
