I think I've found the corresponding file error for every bug I encountered, though I'll probably want to go through COMMU.AFS more extensively some other time.
There were also a number of AFS files in the mod patch that correspond to cutscenes that don't even have Chie in them. I've noted those within my findings.
Two AFS files within the mod have all of the correct ADX files as well as all of the ADX files from an entirely different AFS file. I don't remember there being any issues with the corresponding cutscenes, but it seems weird and it should probably be fixed.
For some reason, V375001.AFS crashes DkZ studio whenever I try to open it. It doesn't crash the game when loaded, but it's still missing an ADX file that causes the voices to mess up.
As for the Nanako text box bug, I think that was a one-time fluke and not an issue with the mod since I reloaded my save and it didn't happen again. (EDIT: This is actually caused by the method I'm using to load the game. I'm using an ethernet connection to my PC, so whenever my CPU is overloaded, the game can't load very well.)
As for V248001.AFS, I don't know what's wrong with it. It contains all of the voice clips for the cutscene that plays on 3F of Marukyu Striptease, so it has to be responsible for the crashing somehow. I originally thought it was because the filesizes were too big, but then I realized that all of the changed AFS files were like that and every other one didn't have a problem. Every .adx file is present and correctly named inside of the modded V248001.AFS file, so I don't know what's causing the crashes. The game consistently crashes on 3F when using a modded ISO, but not when using an unmodded ISO, so I'm fairly certain it has something to do with the mod. Any ideas, anyone? (EDIT: I completely remade this AFS file, and now it doesn't crash the game. I'll chalk it up to an error when the original modded file was made.)
Another interesting tidbit I learned while snooping around the files: Those cutscenes where some shadowy person is walking around the foggy shopping district at night actually have voice acting, but it just isn't used. I guess it was changed last minute to make it less obvious who it is, since it's pretty easy to tell from the voice clips.
