Probably because it was connected to the winding up of service of 1.0, and the 'nightmare' cutscene indeed related directly to it (it was of Nael van Darnus striking the player down after seemingly having slaughtered every other living thing in Eorzea - an interesting metaphor for the then impending fall of Dalamud). Not to mention after the save maintenance SE actually had it that players got relic weapons by checking the bed in that way.

It was a nice little feature, but I guess players would soon end up with clogged inventories if items were given out again in such a way.
