Edits are saved in the wiki no matter how old, new, inappropiate, extensive or short they are, so the only thing you have to do is go back to the revision that featured your edit and put it back in the article, albeit properly referenced.

The lesson here is "to participate in a community, you need to abide by its rules, because that's how communities work."
