Thank you for your reply, but I think my problem may not have been expressed clearly enough, because the problem I encountered also exists when running on a computer. Please let me give an example: for example, when I watched the main storyline in version 0.7.0 and saved it when the story reached the "Memories of the Village" section, I saved a save. Afterwards, whenever I played the game in version 0.7.0, I could load this save and return to that storyline normally. However, when I saved the save folder "saves" After copying to the newly downloaded 0.7.2 version of the game, when I open the "Memories of the Village" save again, the game will encounter an error. At this time, I must restart the main storyline and save it again when the story enters the village section to fix the error. In addition, another example is: when I was playing the 0.7.0 version of the game, I played with a girl and used one of the options. Later, when I used this option on the girl again in the 0.7.0 version of the game, the "Fast Forward" button became available, which allows me to quickly skip the story screen. However, when I turned on the "saves" button After copying the folder to the newly downloaded version 0.7.2 of the game, I went to play with the girl again and selected the same option. However, I found that the "fast forward" button became unusable again unless I watched all the screens again. I wonder if this indicates that the game has a checking mechanism to detect which content the player has not yet completed their "first experience"? Will the record files of this inspection mechanism be saved in a folder?
