We discovered a bug where achievements could not be unlocked during second or subsequent playthroughs. This issue has now been fixed.
After updating the game, loading your save data will automatically unlock any achievements that were not properly unlocked.
For those who have not yet updated manually, please update your game.
We sincerely apologize for the inconvenience caused.
Thank you for your continued support, and we hope you enjoy After He Was Gone.
