So here is my issue. I'm on the Thieves Guild quests. Currently on "Darkness Returns." I walk into the Twilight Sepulcher, and the door behind Gallus to the pilgrim path is closed! I have the journal from the skeleton as well. Now what's even worse, is that I've been in there before, but I was too low level/weak, and I knew it was pointless, so I just went and did other quests. I didn't achieve anything in there or anything. I did my thing, beat the main story line, got my smithing to 100 yada yada, blah blah blah. Now I come back here, and door isn't open. Anyone else with this problem?
