In fact, what I used was savegame32.dat, not the previously provided savegame27.dat. When using the 32.dat save file, on Jade's story line, after I went to Hiyera Debris, I clicked all the red buttons in the elevator and then went to Eden to talk to Elliot, but the plot animation could not be triggered. On Freya's story line, when I went to the motel room, the character's head did not automatically start a dialogue. Accordingly, I clicked on all the clickable items in the room but ultimately could not trigger the animation plot. When using my own save file, I clicked on all the items in the motel room and talked to Elliot in Eden, which triggered the plot animation.Forget it, there's no point dwelling on this anymore. After all, the game progresses smoothly when using my own save file. My only regret is that I can't obtain Keria's blcak desire set. As a foreigner whose native language is not English, the language barrier is also a hurdle for me in playing this game. I raised the issue on the forum with the help of Google Translate and was deeply touched by the enthusiastic response from the experts. Although my response is slow, please accept my patronage.
