Apologies for the belated response and the rollback issues! As a few of our servers were experiencing a few technical difficulties at that time, we were forced to rollback the Player Worlds for one day for all players. Unfortunately, we are not able to recover any of those lost items/Pokemon without a screenshot. If you have any questions or concerns about any of the information I outlined for you, please feel free to DM me! Once again, we do apologize for any inconvenience this may have caused you. Stay safe and healthy.
