Can anyone tell me how to start the Chateau D'Amour quest? Greeting Sylvie doesn't seem to accomplish anything.. And I'm a bit confused about who I'm supposed to reunite, there are two pairs of people in two rooms..

It may be broken, or someone did not finish it. There are love letters hidden in various places, which you'll need to find. Read them, and deliver them. Then do as you're asked - often times delivering an item to who you think sent it.

As to figuring that out, there's two methods. Firstly, guessing. Second, well, I believe Sylvie can tell you how.

it is broken. The last letter is not there. I have checked every nook and cranny of the chateau, and it's not there, i have kept constant watch on it, and it hasn't popped up. I've bugged it.

Ah, these complex quests are so hard to debug it's not funny.

I usually don't say what a bug is, but I thought this was funny. One of the items (a piece of furniture) wasn't flagged right and was being picked up by one of the mobiles!

...THAT is awesome. Pure awesome.
