So I started up a fresh save file, saving right after the first talk with Twilight. Then I closed it and opened up the save, editing nothing but the PCs stats to see if it would work (changed them all to 8). That done, I closed the editor and opened the game back up and loaded the altered save.
It got through the second talk with Twilight just fine, and nothing weird happened in the first Violet Room either. But the next morning, when I had to either look at porn or study to progress time to do anything else, doing either would completely break the game, because time would just rapidly go forward without me being able to do anything.
