Avatar displays for a second before going black

Forced refresh and standard refresh. Only occurs on my own avatar, and everyone else can see it without issue. Possibly unrelated; One member wasn't showing up as logged into the game client while I was talking to him. It was only the one person, everyone else showed up fine and everyone else saw him fine as well.

Same thing happens to me. Has anyone found the solution yet?

Jacob,  Are you using Tokbox for voice? Is anyone else in the group using Tokbox? If the answer to either question is yes then that is why you have no avatar.  As to the second: sometimes' people's avatars do not show up. If person A is not showing up then Person B (the viewer) can refresh and that will often make Person A show up. (I hope that was clear, lol.) - Gauss

Oh, thank you. That was indeed the case.
