Critical Bug: Player Save Data and Persistence Resetting to Zero

Summary The player persistence and save data on my published Fortnite island have randomly and automatically reset to zero for all active players without any updates or changes from my end. Map Code: 3424-1388-0947.

What type of bug are you experiencing? UEFN / Persistence & Save Data

Steps to Reproduce

  1. Launch Fortnite on PC and enter the island code: 3424-1388-0947.

  2. Play the map to trigger persistence devices or save stats/items via Verse.

  3. Leave the match, re-login, or join a new session and check the saved progression.

Expected Result Players should retain their saved items, currency, stats, levels, and overall in-game progression across different sessions through the backend persistence framework.

Observed Result All previously saved data has been completely wiped out and reset to zero for the entire player base without any reason.
