I have this headache bug in Trinity Restored where it is supposed to meet karliah at the standing stones, but the marker it is on the rock for the entry for nightingale hall. Karliah isn't there, it is at the Winterhold Inn and Brynjolf is at the Ragged Flagon. When I go to talk to Karliah she just says 'Hmm..'
I really liked to finish the game and the thieves guild mission but this is just a pain! I was hoping that this bug was to be fixed in 1.5 patch, but as I see i'm very disappointed....
If anyone knows something or share the same problem, pls reply..

So if anyone sees this, and has the same problem, if you don't have previous save to this and want to have all trophies or simply finish all game, here's the solution finish the remaint missions and/or start a new game.
I had more than 110 hours and have had a lot of fun playing the game. Now it is time to change character and try to move to the other legion. This is the good thing about this game, we can try a new different story.

Strange bug, never had this problem on two play-throughs. Note that the entrance to the hall if quite a distance from the standing stones. There is a unique monolith standing stone outside the hall and that is where you meet, not at the standing stones up the hill. Try that first. If karlia is at Winterhold, talk to that elf mage friend of hers, whats his name, and go to the meeting place under the inn there, perhaps something will shake loose. Finally try the force shout on Karlia. Good luck.

Yes, i know that the entrance isn't at the standing stones. I tried all that, talking to the elf mage, talking to brynjolf, force shout too, and I even fight her (even if she doesn't die) hoping that when she kneel down it would repair something, but no. Thanks for the help.

I did not have any trouble with this. Maybe you haven't finished something?

Ok so did you meet first in the theives guild? It is necessary to meet karlia there to get the quest. Silly question but wth.

Yes, of course yes. I initiated the quest a long ago.
