Can anyone tell me how to complete OPQ now?

There's only 4 accesible rooms now, 3 of which don't let us back in after we've gotten the statue piece. Only room we can keep going back in is the one where you have to kill 15 Lioners or whatever, and the room is empty after that. The Round portal in the middle doesn't lead anywhere, and the ladder at the bottom just leads to empty boxes.

Thanks for the help.

I completed it just fine with my Guildies for fun the other day, are you sure you didn't miss something?

Yep... just hadn't talked to the cloud after killing last Cellion, so I had only gotten 1 piece from that room (the one that the Cellion dropped).
