Due to a serious bug regarding our event EP (Event Point) system, our team has decided to temporarily suspend Event Points until further notice.
We hope to fully resolve this bug by Tuesday evening in order to resume normal Event processes. We ask that you please continue playing as normal and we will reimburse all accounts for the lost EP as soon as this bug has been fixed.
Please stay tuned for updates and thank you for your understanding.
-NF GM Team
*Update 3/2*
Due to an unfortunate schedule conflict, our team expects a fix to be ready by Tuesday. As before, please continue playing as you normally would and we will offer full reimbursement as soon as the fix is made.
