Various objects moving on server restart

[Ostentatio 1,971]

Various decorations on my deed have been moving around, seemingly after server restarts. They only seem to move a few inches or so, but this is a pain for objects that are placed meticulously, like lamps against walls, or my weirdly-overlapping copper stills.

This still appears to be happening. I've been testing by moving a couple objects around in my kitchen, and checking them later; some of them appear to be moving a little bit from time to time, consistent with what I've seen before.

 

Is there some kind of rounding problem or other inconsistency between an item's location and its location in the database, or something like that?
