Steps to reproduce:
- Visit any post where a diamond mod/dev/employee left a comment.
- Add your own comment.
- Bask in the temporary glory of vaporizing his/her diamond:
- Reloading brings such diamond back.
(no real diamonds were harmed during this bug report)
Also, all diamonds are lost when clicking "add / show [x] more comments" when post has too many of them. (test case)
Also worth to mention it affects both full site and mobile site themes, so it's not just a CSS issue.
