I am physically stuck in The Shivering Isles..

[Kris P Lettus]

The expansion pack for The Elder Scrolls IV: Oblivion.. I've pretty much beaten the whole game minus the Mages Guild and a few random "fetch it" side quests (e.g. Museum Of Oddities, Job is Never Done, etc) so I've been just going around exploring areas and whatnot.. Anyway, I went back into the Shivering Isles and decided to go re-explore the Garden of Flesh and Bone just to see if I had missed anything.. I go inside the dungeon and get to one of those vine gates at the end of the first section Natorium of Well Bled Tears.. I pulled to switch just for shits and giggles and the vine gate closed.. I move on to the second section Conservatorium Corpusculum, and there is only ONE door leading out of that area.. I explore and get to that door which leads to Caverns of Susurration.. Going into that area there is another CLOSED vine gate just inside the door.. No switches or anything.. I go back and that first vine gate will not open.. I can not fast travel from here and I had just cleared out all my save files (which I tend to do everytime I play) so I am physically stuck in the Conservatorium Corpusculum.. Anyone have any suggestions or thoughts?? This might just be a glitch and I might just be fucked..
