The title says it all. Also this post contains SPOILERS sort of so if you don't want to be SPOILED, then I recommend not reading the rest of the post.

After going through the dead nations and coming to the drowned nations I found the nameless one's tomb where you are teleported around while having to collect 3 keys. After collecting these 3 keys I am able to enter the middle room without getting teleported anywhere and I am also able to read the signs on the walls. According to several walkthroughs I am supposed to examine and press all of these signs in order to get the sarcophagus in the middle of the room to open. HOWEVER after doing this the sarcophagus in the middle of the room still refuses to open AND THE DOOR OUT OF THE TOMB IS STILL CLOSED, meaning that I am stuck. I have tried downloading fix packs and I even started the game from the beginning BUT THE TOMB IS STILL BUGGED!

PS. After pressing all the 4 different signs in the room, I can still press the one to the bottom left as many times as I want. I guess this is what causes the bug... Also if I keep reading the signs and the sarcophagus several times I am sometimes able to push some of the other signs in the room again afterwards.

Is there anything I can do to fix this or do I have to restart the game yet again and avoid this tomb like the plague?

Upload your saved game someplace and I'll have a look along with your weidu.log (found in same folder as Torment.exe). I don't think Qwinn or I did any work on tomb area. My guess is you're not doing something right but it's been awhile since I played so will need a save.

I've attached 2 saves here as well as the weiDU file, just rename saves.png to saves.zip
The save Laks is the one I made during my first attempt with the game unpatched after installing from GoG.
The other save named Laks 2 is from my second attempt where I tried downloading a fix pack as well as the book of cheats (was hoping I'd be able to summon the tombs keys... unfortunately they are not included)

It would be nice if you could tell me if I am doing something wrong...

I only tested the game with fixpack save and its working fine. I was able to get out of the tomb. I'll give you a hint, look at the panels on sides of the center room and see what they have to say. If you're still having trouble, you can always consult a walkthrough. Although, I would advise against this because it ruins figuring it out on your own. In short, no the game isn't broken. :)

I found out what was wrong. I thought there were only 4 tablets on the wall as they were sort of connected and the walkthroughs I have consulted have also only mentioned four tablets.

It does however seem that there are 8 tablets (each tablet is split in two)

Well, I'm at the same point in the game and -have- discovered a "game-breaking glitch."

I've got all 4 portal keys, but am not teleporting to the hidden room. ~__~

I know this is a really old thread, but I've just been in that tomb and I think I know what the problem was. There are total of 6 walls of text, not 3 as I first though. They are arranged as 3x2 and when you hover over them, it's not completely obvious that the question mark cursor doesn't just refer to both of those walls as one.
