So I remember in the first area that the 4 doors need to be situated a certain way...I closed the hurtful door and its opposite, and opened the other 2, like the UESP walkthrough says. Didn't do anything. Then another walkthrough said to only touch the southern door. Thing is I can't remember how the doors were configured in the first place. So...what configuration do the 4 doors need to be in?

I already pulled the switch on the little floating island at the top and the switch inside the lowest island. Now it's just the doors I need to deal with.

Ok, I figured out the first part. I actually had to make sure all 4 doors were closed...something which none of the walkthroughs said to do. SO maybe the required configuration changes from game to game.

Anyway, now I'm stuck in the pyramid part...I clicked on all the gravestones, but the trap door inside the pyramid is still shut. Clicked on all the gravestones again, and the trapdoor is still shut. Gamebreaking bug possibly? I hope not.

I wondered about the 4 doors as well, and it seems either the UESP walkthrough is wrong, or the solution changes between games (probably the latter. Another walkthrough I found on the net had yet another solution). In my case I had to close all the doors except the hurtful one, which I didn't touch (all the doors started as open).

I ran into the pyramid bug as well and found no way around it. The game can register too many clicks in a row and open-close the trapdoor when you think you only clicked once. However no matter how careful I was, or how much I reduced the game speed (via DOSBox) the 2nd trapdoor (at the bottom of the pyramid) stayed shut. The only way I found around it was to get someone else's save.
