Hi!
Please note that Fern-related content has been completely removed from the game in the latest version. It is no longer part of the quest flow.
If you are using an old save, it may still reference removed content, which can cause the looping issue. Unfortunately, this cannot be fixed on existing saves.
To continue the story correctly, starting a new save is required. The loop has been fixed in the current version, and I’ve confirmed it through testing.
Sorry for the inconvenience, and thank you for your understanding. 🙏
