I did a search against the armory (both web and app) and found an entry for my character (level 85, night elf, druid) as reported by the list but on opening the entry the data shown was for another character. This other character is a level 14 (when last seen) night elf, hunter with the same name, Moong, also on Anvilmar.
If the level 14 character is played by whoever owns it, I notice my characters information drops off the Armory app and the other characters data is displayed when I search for the character name. I am also not able to access my auction data as well. If I play my character, level 85 Moong, that data gets displayed not to long after. After playing I am also able to access my auction data.
Without knowing the inner-workings, to me it would appear there are 2 characters with the same name on the same realm. Support says they only see my account and suggested I post my question here. I am still able to play my character, just unsure where the other characters data is coming from, if not on Anvilmar.
