I just installed this mod a few hours ago and been fiddling around on Throat of The World for a great bit of time. I can't find the portal. I searched the entire peak, even found the Notched Pickaxe (which I didn't know existed, even) and I've found nothing. I've walked the road from Paarthurnax to the Grey Beards and back, I've re-installed the mod and I've restarted both game and computer now. I even fell from the Peak a couple of times and had to summon Aadvark to ride back up again, and it still wasn't there. I've already killed Alduin (about 20 ingame-hours ago, I believe, maybe more). I'm not fond of losing 20+ hours, several campaign quest-lines and about 30 levels to enter a giant (and very beautiful) player-house... Is there anything I have overlooked? Is it possible to add the portal spell via the console? Or should I just forget about the mod all together?
