So what should I do?

[fv-2020]

I was playing survival and while I was exploring my internet disconnected. Why I joined back everything was gone. My items, my levels and my skin had changed only for me. The only thing remaining was that I was still part of a clan and I had my money. A MC restart only fixed the skin problem. So is this irreversible or can it be fixed?

The only reason I think of for this case is you died (something killed you or yeah...)
