Where did all of the Lifetime membership icons go?

It has happened to me occasionally, just logging out and back in cures it for awhile.

Strange, I went and viewed my profile and signature. This required me to log back in. It said life member there, so I came back and looked at this post again. Now it says "life member" again. What was odd was that I couldn't find any life members before not just me. Logging in again shouldn't affect the member icon that I see for others?
