We have confirmed an issue of an error (0x0951) occurring when opening the bag.
There is a possibility of an undefined item being selected by opening the "Leo Box" that can be acquired in the game.
Please do not open the Leo Box until the fix is made.

We apologize for the inconvenience caused by this issue.

Currently, we are working on investigation and fix of this issue.
The issue will be fixed in the game maintenance once prepared.
