This was a shame, and I could have lived with it, if it was only that one object... but then I wanted to show my friend something else, and I got the exact same message... starting to seing a patern here, I startet testing everything I've made in the last year (I'm a scripter/builder) and pretty much everything was "missing from database".
I then tried loging out, clearing my cache and loging back in... which turned out to be a very bad idea, as when I loged in, I got the message: "Replaced missing clothing/body part with default" (got that message about 10 times)
so now, I'm partially white, my clothes is gone, nearly all my builds is gone, and about half of my scripts is gone...
my question is, is there ANY way to recover this?
I have tried using the SL Alpha build on linux, to see if it should be a freak client problem, and I've tried transfering some of the "bad" objects to a friend of mine, but without any results... it's still all gone

(and of course, I've filed a support ticket, but as I'm only basic account, I don't know how long I'll have to wait, if it will help anything at all)

EDIT: btw. all the stuff still show up in my inventory, it just wont rez, load or show. (the messages)
