Forum:Some issues creating a disambiguation page...

I was editing some content recently, in short, here's what I did: So now what do I do? How do I create a page named something if the name is and is not already taken at the same time? Is the new page name only superficial until the page is moved on the server or do I have to change something else? Please assist. —This unsigned comment is by SimonKTemplar (talk • contribs).

 * The wiki I'm working on has 2 distinct pages of similar content: Fly Amanita (Skyrim) and Fly Amanita (Oblivion), however, the one that is now called Fly Amanita (Oblivion) used to be called just Fly Amanita (without the suffix)
 * So I renamed the page called Fly Amanita  to Fly Amanita (Oblivion). HOWEVER, when I try to create a disambiguation page entitled Fly Amanita, the wiki reports that there is already a page entitled that, and when i type in that page in the search window it redirects me to the page I just renamed, namely Fly Amanita (Oblivion).
 * Go to the redirect page and turn it into a disambiguation page.--
