So after the recent maplesea update, I logged on and tried to do this quest. I got to the part where I had to kill the lock and enter the room, then click on the chest. But after killing the lock and going inside the room, when I clicked on the chest maplestory would crash. When I logged back on I was stuck in that room. I tried leaving but they said the mobs were too strong. So I accepted a maple administrator quest and got out of there.

Now my question is: How do I get to that place or how do I complete the quest? I can't forfeit the quest to restart it.
