Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

A couple of times, I've noticed users who'd been wearing hats suddenly not wearing hats any longer. This appears to have been the result of reloading their posts via the "This post has been edited" notification.

Refreshing the page entirely restores the hat. Seems like a bug, but I'm not finding any previous meta questions about it.

The JavaScript to insert hats onto the page is only ever run once - when the page finishes loading. Any time a Gravatar gets added (or in this case, replaced) on the page, it will not get a hat. This is just another place where adding code for hats is simply not worthwhile.
