Gryphline‘s free-to-play action role-playing game, Arknights: Endfield, has launched with a bug that randomly bills players for unauthorized payments.
The launch of Arknights: Endfield was quickly overshadowed by a major payment system bug that left players facing unauthorized PayPal charges, raising serious concerns regarding account security. Within hours of release, players began reporting that PayPal payments were behaving erratically, with purchases appearing on accounts that did not initiate them. In some severe cases, players discovered that their saved PayPal accounts were seemingly linked to other users, allowing them to purchase battle passes, monthly passes, etc.
The bug pointed to a systemic issue rather than isolated account compromises. Some players reported waking up to find a large sum of funds deducted from their PayPal account overnight after making a single purchase and logging off. Content creator fobm4ster appeared to be affected live during a recent stream, discovering that purchases were being made with his PayPal account without his authorization.
In response, Gryphline issued an official statement on Twitter/X, acknowledging the issue with PayPal payments. According to the developer, the problem involved an “inconsistency between the order and item delivery” and affected a “limited set of orders.” The company provided a detailed timeline, stating that PayPal was disabled as a payment method shortly after the first reports were confirmed and that all PayPal transactions within a specific time window were reviewed. Full refunds were initiated for all PayPal orders created during that period, with the developer stating that they would be completed within 4 hours. PayPal payments remain disabled until the issue is fully resolved and tested.
While many players welcomed the refunds, some affected users reportedly received refunds not only for fraudulent purchases but also for their own legitimate spending. The community criticized the developer for stating that the incident affected only a “small number” of purchases, as the scale and severity suggested a more widespread issue.
