Objects repositioning themselves!!

Hi

A few times recently when i have logged in - i have found objects (owned by me, on my land - and NOT set so anyone can move them) repositioned. Not far from their original location, but far enough for it to be very annoying.

I found a section of a building had shifted a few metres on one occasion, and on another a piece of furniture had moved a couple of metrees upwards and to one side.

How is this happening? Is it being done by someone? Or is it SL related?
The land is set to 'no scripts' - and is mainland (class 5 sim).

Thx!

I haven't had them move like that, but they've flipped slightly in rotation. I've bug reported what I see (and suggest the same to others with problems).

As far as my situation, it's SL being SL. Tiresome.
