Sims 3 World Adventures China - Dong Huo's Treasure Trove?

In Sims 3 for the quest to find Dong Hou's treasure on the Curious Note quest in the tomb under the market, I've been able to access all of the rooms (I think), even the one where you get the relic symbolizing you completed the quest or what not. However, there's this one blacked out room I'm noticing and I can't figure out how to get into it. To better clarify, this room is closest to the long hallway full of traps that you use the four keys to disable. It's off of the actual treasure room with the leopord print throne chairs where there's the arches leading to the 6 rooms where additional treasures are. From one of those rooms there's these red awning/curtain things just hanging there and a wall with a torch on it, and the black room is right next to this room, and appears as if it should be accessed from here but alas it is not. Sorry if all that explanation makes no sense. I'd upload a picture of it if I could but it doesn't look like I can do that on Yahoo Answers. Anyone know what I'm talking about, where I can get answers or give me any ideas for how to solve this? I'd really appreciate it! Thank you in advance. This thing is driving me nuts!
