right... im on the thieves guild quest titled 'Blindsighted' upon walking into the big open area with the statue, dialogue flows as normal until mercer says: "Karliah when will you learn you can't get the drop on me.." then nothing.. absolutely nothing.
i have tried console commands to add player controls to let me just leave the area.. but then i get brought right back to the same bug ridden room.
i've tried loading up a previous save and replaying an entire hour of the game in hopes the bug would fix but no. tried spawning all the ai characters in the cutscene to me, nothing. i've paid ￡30 for a game which i can no longer even play. what the [censored] is this [censored]?
this is a complete joke. bethesda, if the game wasn't even working properly then why do you deem it fit for release? not even like it's a minor quest... the thieves guild is a major questline... one would expect you to have ironed this [censored] out before release.

anybody at all got ANY fix?
I know i'm not the only person with this problem.. but finding a fix for it seems to be impossible.

HELP PLEASE!?

BUMP FOR FIX

bump

Ive had the same problem, on PS3 though. Plus I saved right before I entered the room so I cannot even get out now. So I have resorted to starting a fresh game

Finally someone else with the same problem. I don't know what to do. Bethesda Tech Support said to wait for up to 30 days. I tried that, then 60, then 90 with no luck. I'm stuck in an area and I can't get out.

Has no one else had this problem? I've tried the crash thread but there is no help there either

A few console commmands, perhaps?

1st - check your quest stage -> getstage tg08b

You may be stuck at stage 35, which contains the scene you mention. If so, try -> setstage tg08b 37

This should trigger the water rising, then lead to stage 40, where player control is restored.

It worked to move the quest forward, the problem is that Mercer Frey is just not in the sanctuary. I tried the player.moveto command and it takes me to the windhelm stables every time. I don't know how to fix this one.

It is noted that if you are in sneak mode while entering this final room, it may not work. See this for more information: http://www.uesp.net/wiki/Skyrim:Blindsighted#bugs

BUT - this may also be related to an earlier incident in the caves which is supposed to happen: http://www.uesp.net/wiki/Skyrim_talk:Blindsighted#Mercer_not_there

It sounds like this second link describes your situation more closely.
