Clone, I still have my street creator trophies from the first beta, so you should also still have yours. I recommend reporting it as a bug, as I said, so that someone has to take a look at it. Also, stand in your house for awhile before assuming things are missing: sometimes they take awhile to load.
It sounds like Clone had trophy pieces that hadn't been formed into the actual trophies yet. One or more of the 3 people who had keys to his house might have taken them.
Calm down... I relocated the stuff to a safe place, so someone else wouldn't jack your stuff. Just meet me next time online, and I'll return it, or if I still have your key, then I'll drop it off. I had no idea who else had your key, and since you weren't online, I rather have you go through hell temporarily, then for the rest of your Glitchy Days (should you come back, which ya did).
