Title may be a bit confusing, so i'll explain as well as i can. Moderators and Administrators can select multiple topics by hitting the checkbox next to the topics, which should make the box appear to allow you to do several actions. However, that very box only shows as a thin 2 pixel high line for us. This has been a bug for a while now, though we can't seem to figure out how it happened and how to fix it.. The permissions are fine, as everything works fine aside the box itself.
