On various avatars that don't share any items, I occasionally seem to lose gravity. It's been happening since last year, but it's only once or twice every other month so I haven't been bothered much by it. My friend's usually can jump on me and push me down or kick me away like a balloon, so it's not lag I think. I use Firestorm and Firestorm beta, and due to the rare-ness of the problem I haven't tried other viewers. It's a neutral gravity, so momentum and being pushed dictates which direction I float in, and I use a floating animation. If I go into flying mode I can control myself and land, but if I walk or get pushed it might happen again, but relogging tends to fix it. When landing I can usually tell if I'd fly away again because while standing I will hover up and down slightly, or a lot if I stand still for a long time. The only abnormal thing I think I have is a large messy inventory, which I don't think could be related. I will bounce off sim borders and resume floating in the other direction. I don't know of any items that I own that could do this, and I'm certainly not wearing any. Usually happens when in-sim teleporting (double-click, move to, etc, not landmarks) and especially if I'm in a building (or just hollow mesh cubes even). It's happened on multiple sims. The closest thing I saw was when someone in 2007 saw they were wearing a gravity item. But I'm not? What is causing this weird issue?
