crashed then show invis to friends?

Hi, I was having an issue today with SL using the Emerald Viewer and when I crashed and logged back in it showed me as invisible to everyone on my list from wht I was told, even though I never set myself invis, anyone else had this issue or something like it? Basically trying to clear my name with someone who thinks I am lieing to them. any help would be appreciated, thank you.

I had a crash today and when I relogged I realised I wasn't really connected properly as I wasn't getting group notices. After I logged again it was fine. What happened when you relogged the second time - was it the same or back to normal?

Well, when I logged back in again it seemed okay. did not seem to be giving me any problems.
