Finally obtained the Order-Etched Galary Rail lead from the Bad Man's Hallow Public Dungeon, scryed it, excavated the item. After that I obtained the Pale Order's Golden Band lead from the Arkthzand Carverns, the last item I needed for this ring. So I excavated the item and expected to have all the items to get the Ring of the Pale Order. But the Order-Etched galary rail had disappeared from my obtained items. This is really disturbing that items just can disappear like that.
I like eating sweetrolls and crushing skulls, and I am all out of sweetrolls.
