Save the World has been disabled while we investigate issues with the Stormshield Storage and the Frostnite mode.
Quick update.
We disabled Save the World as Stormshield Storage was being wiped by playing the Frostnite event.
We are currently confirming that there is no other source of data loss and are going to disable the Frostnite event and re-enable Save the World after we are confident.
Next up, figuring out what we can do for players impacted by the data loss.
