Disappearing roles

In the latest update, version 3.01, the user roles of anyone contributing to a ticket are no longer displayed.

The culprit is lines 1336 to 1339. Why have you changed this code? If you change it back to how it was before, specifically:

if (isset($author_data->roles[0])) {
        $role = $author_data->roles[0];
 } else {
        if (isset($author_data->roles[1]));

it works as expected.
