This addon will prompt you that your housing buff is missing, if in fact it is missing. It will prompt you any time you enter a housing sector. If you want to ignore the alert for the remainder of your session, there is a check box to do so. This may be useful if you've "bugged" on the buff, lost it, and it's still not available till next reset. Then you can disable the alert for good if you want.
Command Usage
/buff will re-enable the alert if it has been disabled.
/buff unignore will re-enable alert for the session if you ignored it (useless but hey, its there)
