I noticed with a friend's avie that he didn't always look the same. I know exactly how he looks, but sometimes his shape seems messed up. Upon taking a closer look at this, I saw that his face is still the same, but the body is different. He is smaller, and the torso length is lower! And vice versa he noticed the same thing with my avie.
This is pretty scary. It leaves me with a bad taste of never knowing how I am actually gonna look like to other people. I may look all fine on my own screen, but who knows if I load correctly for other people. Same thing with hair, sometimes it just doesn't seem to fully load. For a while I thought that these people with messed up hair just hadn't adjusted it right, but it's not true. It was probably fine but just not displayed correctly for me.
Just another oddity of SL?
