I'm not sure how to report a bug. It looks like if you edit your post the user's avatar image becomes their blog thumbnail. It has not only happened to me, but I'm seeing quite a few posts from other users showing their avatar as the thumbnail in the VYB feed as well, but it's not an image used in their posts.
I originally edited through Peakd, when I looked at it from the VYB front end my avatar was the thumbnail and only the description showed when I opened it. The whole post body beyond that was gone. I edited it from the VYB frontend and the post took, except the thumbnail.
Thanks

Now my post won't load at all
