I've just downloaded Shivering Isles on Oblivion Xbox 360. I can't wait to visit another realm! When I got the quest to investigate the secret portal, I traveled to the Bravil Stable and I saw a yellow blob up ahead. I went closer and then I saw this:
These yellow triangles with purple exclamation marks. That was where the portal was and now this! How do I fix these exclamation marks?
