Hello Tamers. This is Digital Administration Bureau.
We confirmed that the Battle Pass reward from Yagami Hikari is marked as Season 1, not Season 2,
It has been fixed through the current live patch, and you can receive Battle Pass Season 2 rewards normally when re-login after the client update.
Sorry for the inconvenience and appreciate your understanding.
Feel free to DM the GMs if you have any questions
Digimon RPG Support team will always stand by to help you with the best effort.
Thank you.
