I got the Word of Crota he other night, after returning to the tower I noticed my Word of Crota previously equiped was now replaced with the Hard Light in my in my inventory. So, I check my Post Master, my Vault, and my other two characters. Later, when rechecking my Vault, guns began to flicker. In and out of the inventories of my Warlock and Titan. Not too much later I check for a few Relic Iron, only to find my Vault completly empty. The weapons, general items and gear all scarttered throughout my three characters, and I still have yet to find the Word of Crota. That was a gem to me, especially after the release of Crota Hard and doing in every week on each character only to obtain the Fang with every completion.
