Before you read, this took place on May 22, so you may not remember editing this page. :)
Recently, there have been some small category issues when editing pages. A few users (including you) have edited a page (in your case, it was adding information about Pancakeria HD to Vicky's page) and when you clicked publish, it renamed a category for no reason!
When you finished editing Vicky, it renamed the category "V Characters" to "V Charact."
We know that there is a very small chance of it being your fault, since it has happened with other users as well. The other user I have also messaged is Sugarplex Fan, who has encountered similar problems on different pages.
Question: Were you aware of this problem? :)
