Help! All character progress gone.

So earlier today I logged in and my characters were level 0, but it was whatever I hadn't played long. Spent quite a while playing today and when I went back in my newest character and all items were missing. Why does this happen and can it be fixed?

Is it possible you were playing on open or local mode when you made your progress?

Anyway, there is no data on the server to be restored, unfortunately.
