112Cloaking Speed Discipline shows up in a Rogue's missing spell list from the /output missingspells command. I believe that the disc was in Beta during ToV for rogues but never made it to Live. But the entry in the spell list must not have been corrected. [Note: there are a number of missing spell list errors like this across classes. Would you prefer one entry for all, one entry per class, or bug report them individually?]
