If you have recently earned an in-game reward though an event or ranked season, you may get an error when trying to equip the portrait, monument, or coat of arms that reads “Couldn’t edit or save item” and gives the error code C19T04R00X-01 4974656D04BC. This error should clear itself but may require a restart of the title and some time from when you initially earned the reward.
If the issue persists for more than 24 hours, please Contact Support with a copy of your Warning Logs. We are aware of this issue and are working to resolve it as soon as possible.
