I (accidentally) killed Karliah just after going into Nightingale Hall for the first time during Trinity Restored / Follow Karliah. It marked the mission complete and it appears I am to proceed with the next objective; Activate the Armor Stone.
Not sure how to fit this into existing Wiki Page.
Updated with new information Edit
NEW SAVE before getting nightengale armor on. Karlia walked off somewhere without pulling the chain! Fixed on PC by going through more dialogue options (Don't just answer "Yes, I'm ready."). Go through dialogue than let her lead to chain. Fixed!Usafirefly (talk) 14:04, September 24, 2014 (UTC)
Bug: Can't stand on glyph with AFT mod enabledEdit
When the Advanced Follower Tweaks mod is enabled, Karliah won't open the portculis when you reach the task Stand on the Vacant Floor Glyph.
The workaround is to disable AFT and restore to a save before the task. Documented here:
