We are currently having issue with the bonus mileage event. We are aware that whenever you purchased
in game cash items, you only acquired 5% bonus mileage instead of 10%.
We apologize for the inconvenience. We will be giving all the bonus 5% mileage that you were not able to get at the end of event date on March 18th during the weekly server maintenance.
Once again we deeply apologize for the inconvenience.
