Hello, this is Prettybusy. 

We corrected the error by finding out that there are some players who are unable to initialize their weekly achievements due to errors and are not receiving compensation.

For those who have previously experienced difficulties earning weekly achievement rewards, we have provided all users with [weekly achievement rewards] x4 weeks through the mailbox. 

Weekly achievements will be achieved normally from next Monday (KST). 

We apologize to everyone who experienced any inconvenience, and we will continue to solve the problem meticulously. 

Thank you always.
