Who Am I? Bug

I don’t even know if this is an actual bug, but for about the 10th time I have noticed mine, and a few other members WAI disappearing for a couple refreshes.

I notice it gone after Quick Replying, then editing without refreshing. Not really a big deal for me.

That’s happened for about over a year now.
Not really a big deal.
Also happens after editing your post.
It comes back though.
