Alright, I see you already removed the other font imports from Common.css, so they shouldn't be available now.
It looks like you are attempting to import the Sanchoz and Texturina fonts three times: One from a file on Common.css, one from a file on Wikia.css, and one from Google Fonts, also on Wikia.css .
In addition, having code on both Common.csd and Wikia.css causes issues.
I suggest you transfer all code from Common.css to Wikia.css, removing the @font-face statements for fonts you are already importing from Google, and make sure all @import statements are at the top of the page.
