No need to apologize here. As long as you, Basilbrush, and anyone else involved from that wiki have settled it, the issue is done and over.

For future reference, the reason it didn't break anything right away was because of the server's page caching. Depending on what is on a page, it can take significant computation power to render the content sent to a user's browser. So, to decrease server load, each page is rendered and then that rendered version is saved. When a user views the page, they are sent the saved version. Pages are re-rendered either when an edit is made, it is forced to do so via the "action=purge" option in the URL's query string, or a certain amount of time has elapsed since it was last rendered. If you want to know more, you can read Help:Purge.
