Done Dead after restart???

So the server restarted when i was hanging out on a friends island flying around. I join back in and it said im dead. Quest book said i died by void but i was alive before the restart! Most important items are: Ring of Flight, Ring of Magnetization, a flint mattock with repair 1, reinforced 1, and a diamond, and 6 stacks of stone slabs D:

 

ok a friend helped me find my gravestone and get the items back
