Here are the patch notes for this morning's game update (as posted by Piestro over on the EQ Forums):

*** Emergency Update ***

- Corrected a bug that was causing framerate/lag and texture loading issues.

- Players on Progression servers should now be able to use automatically-granted AAs (such as Harm Touch and Lay on Hands) before Luclin is unlocked.

*** Progression Servers ***

- Translocators will no longer offer to send players to zones that have not been unlocked yet.

*** Quests & Events ***

- Terror in the Dark - The raid has been repaired and should function normally now.  All tentacle terrors will need to be killed along with the final boss in order to complete the event.

- Ritual of Terror - General Grime's Glyph of the Horror will no longer be a possible requirement for defeating the auras of the Tae Ew leaders. 

*** AA ***

- Shadowknight - Early ranks of the Harm Touch AA have been scaled back in damage on the Progression servers. 

- The EverQuest Team
