"You can't complete the last part of the Eliminating the King Sage Cat quest because you can't enter Hidden Street: Forest of the Ghost Priest. As http://bbb.hidden-street.net/quest/mu-lung-nihal-desert/eliminating-king-sage-cat lists, as you enter the map, you get a notification from the Maple Administrator to go into the Forest of Ghost Priest. But, as you cannot enter that hidden street, the quest ends prematurely." So, yeah, that hidden street map still isn't working, although this post was made back in 2013. Hoping to see a fix sometime, the rewards are 17 (!) fame and ~275k EXP (x4), so there's 1m exp sitting on the table ^^ Also about to post this in the quest bugs list thread.
