There's a new bug in your contributors list on a project main page: it's only showing small subset (typically 1) instead of the full list as it did before. Here's a few examples:
I'm seeing this same issue all over the site now. Minor contributors to projects are being listed on the main project pages as the sole contributors. Have a look at clojure's contributor icons: Rich Hickey isn't among them!
That certainly looks like a bug to me. Thanks for reporting it, we'll look into it :)
