We have identified an issue where the data in the "Collection" section becomes corrupted when upgrading from version 1.0 to version 1.1 or higher after creating save data in version 1.0.
Unfortunately, it is difficult to fix or restore this issue. We sincerely apologize for this inconvenience.
To help restore the situation to some extent, we have added a one-time process to add points based on the achievements currently unlocked:
No achievements: 20,000 points
Achievement for collecting 20 or more items: 60,000 points
Achievement for collecting 40 or more items: 120,000 points
Achievement for collecting 60 or more items: 160,000 points
Achievement for collecting 80 or more items: 400,000 points
Achievement for collecting 100 or more items: 2,000,000 points
The release of this version, which includes this process, is scheduled for JST 6/22.
We deeply apologize for any inconvenience caused.
