Its official. There is no skyshard in cryptwatch for. Checked online for where it is supposed to be as well as combed every inch of the dungeon 3 times over. Its not there. Put in a ticket and the GM told me to look harder.
I just went through this last night. The gem has been moved deeper into the new part of the dongeon. It is there, in a room between the old location and the open area where the boss is. Keep looking...the info on help sites is outdated.
