Died to a Dragon from ice and fire and died in the water. Gravestone is gone and nowhere to be found. I have my obituary that says the coordinates and no gravestone. Is there something that happens when you die in water?

What probably happened is the dragon destroyed my grave and my stuff despawned

You may also report this to the ice and fire devs, as the mod should not destroy this block.
