Nerfed?

I recently ran the statue with a group of my friends, and we didn't encounter a single group of ghosts! Did Nexon nerf the statue dungeon at some point?

Might've just been luck, but we'll need more tests to confirm.

I have done a run in November 2011, and there were ghosts. If it was nerfed, it must've been a recent update.

Are you sure it was a glowing statue dungeon? What was the boss you encountered?

In my case, it was the completed glowing gargoyle was helping someone get transformation.
