Hotfix 10/11/16 - Grouping Issue in CyrodiilEdit
Tomorrow beginning at 6:00am EDT, we'll be performing a hotfix to partially fix the issue where you're removed from a group after using a Transitus Shrine in Cyrodiil. However, please note that there's still an outstanding issue where you can be removed from a group if someone in your group is offline, and you use a Transitus Shrine or resurrect at a keep. We're continuing to work on fixing this issue, and plan to have a fix in an upcoming patch. In the meantime, we suggest the group leader remove any offline members from the group to prevent this situation from happening.
We're continuing to work on a fix for the EU realm selection issues, and will roll that out as soon as we can.
The hotfix for the grouping issue will require some downtime (only on PC/Mac) which could last approximately 3 hours. We'll let you know as we're nearing the end of maintenance.
