It's common knowledge that certain main line quests tend to bug over time. Two most "popular" examples are the infamous Sacrificial Lamb in Limo and Battlelines on the Brink in Chrysalia. And progressing without them is really hard. This is especially frustrating during exp events when lots of time is just wasted due to bugs. At least this is true for Vidar server.
Players use the support tickets, IRC chat, even world shots for GM but in my experience this usually takes really long and often people have to wait till next scheduled maintenance.
However it can be fixed just by restarting the zone which can be done by a system administrator (I'm sure there's someone to watch servers and fix if necessary) and hopefully doesn't require GF CEO authorization.
Could you please introduce a reliable routine for quick zone restart? Maybe some GM can regularly check the iRC for relevant messages? Or it can be a one-button web interface for the two mentioned quests. These bugs can usually be quickly verified by any person in the zone.
