"Bug Hunter" badge icon is broken

Steps to reproduce

Go to Dynalist Forum (or even just Dynalist Forum):

Expected result

There should be an icon (presumably this one) next to the title and description.

Actual result

There’s a “broken image” icon instead.

Environment

Ubuntu 18.04, Chrome 71.

Reporting a bug about the achievement for reporting a bug

Looks like this got broken when we upgraded Discourse (the forum software) a while back.

Looking into it!

Fixed! Sorry about that.

This badge was created way back when the forum first started, back when we manually grant this badge to everyone who reported a bug. Nice catch!
