Server lost mod related world items!

[Cold Evil]

Hi i have large issues!

I restarted my server when the world were loaded the entire world were emptied out from all mod equipment and resources. only leaving the shell of vanilla stuff.

In panic i force stopped the server to prevent the world from loading.

Is there a way to back the server to a previews time?

Add: This also means that all ore and stuff also are lost in the near by sector...
