The LOTRO Game Servers will be brought down on Tuesday, January 26 from 8:00 AM - 10:00 AM Eastern (-5 GMT) for a server side hotfix to address the Barad Guldur Gate Issue.
Players who enter the Barad Guldur raid instance with a previously obtained raid lock may encounter an issue where, upon a group death, the gates earlier in the instance no longer lower. This will prevent the group from returning to their previous point of progression and continuing.
The recommended work around is for players to exit the instance, disband and reform the raid under a new raid leader. This will reset the instance and lower the gates. However, any ‘trash’ mobs prior to the next boss fight will respawn as a result of resetting the instance.
