Hello and thank you for this great plugin.
I'm having a small issue with the avatars not being displayed after submitting a comment. I ran the debug mode and all the selectors are found. I'm using a child theme of the tewntytwelve theme. My site is currently installed on a local dev environment and unfortunately I can't link to it.
After a page reload the avatars are displayed as they should.
You can view the screenshots of the console log and a test comment here:
