That is actually caused by the new Visual Mode editor, which everyone gets by default unless they turn it off in their preferences. Wikia says it happens sometimes if a person saves their edit before the editor finishes creating the preview. I think you're supposed to wait 5 or 10 seconds before clicking on Save to keep this from happening.

The Visual Mode editor isn't very intelligent in another way: when you put in a picture, it may insert the code for the picture in the middle of a word. Example:
 *  Candace was wa[[File:Candace.jpg]]lking to the store. 

It displays fine on the page, but it makes editing it a little harder.
