Maintenance for the week of November 17:
• PC/Mac: No maintenance – November 17
• ESO Store and Account System for maintenance – November 17, 6:00AM EST (11:00 UTC) - 4:00PM EST (21:00 UTC)
• Xbox: NA and EU megaservers for maintenance – November 19, 4:00AM EST (9:00 UTC) - 12:00PM EST (17:00 UTC)
After I updated my quests all say unknown quest and when I go to the crown store the description for things is blank; as is everything else.
I also have no audio.
If NPC's are showing up as 'offline' it could just be your are experiencing some intermittent connection issues. The first thing you should try is simply logging off for 15 minutes and then logging back in. You may also want to try switching between Megaservers as well.
