I got a beautiful mesh body (TMP) that keeps disappearing. I look fine for me on my firestorm viewer, but others see a large hole where my body should be. I have to relog for it to come back. I realize many have this issue, but my avi loses her body pretty much every time she teleports to some where else ( well not always ). Am i wearing to many attachments? Is it my viewer? Is it my internet connection? Help tired looking like a ghost. I changed viewer and up dated my flash as well...same problem nothing has changed :( I am using windows 8.1
