[Opensim-dev] Viewer doesn't render attachments after teleport

[Justin Clark-Casey]

I also used to see this issue a lot when testing attachments.  At the time, I remember looking into it and adjusting a 
few things to make OpenSimulator's output packet order match LL much more closely but with no effect.  I haven't seen it 
for a while so I was hoping it had gone away, though that may also just be because I don't get the chance to go in-world 
very often.

One possible thing to investigate is whether SOG updates with a position of <0,0,0> are somehow getting out to the 
region before attachments are properly set up.  This might account for audio issues, etc.  It might also be a shot in 
the dark, though I think this used to happen under some circumstances (along with other effects such as HUD attachments 
wrongly appearing on other viewer's screens).
