My Sharp 10 Iron Sword disappeared

So I was walking around spawn, then i went back to my base, and my sword was gone. Idk where it went. can i get a replacement or get it back?

I doubt the server refund lost items but good luck

 

Unfortunately that is not something staff can sort out, as bever46 says.
