I just noticed an anon helping to edit Kassadin's page, to change the name back to Kassadin from Draven. Comparing the two edits in the edit history, I noticed that the categories 2009 release, Beta stage release, and Released Champion were accidently deleted from the bottom of the page.

This isn't the first time I've seen this happen (I've made this mistake too in the past), so is there any way to prevent this from happening? Many edits happen to this wiki every day, and it's likely that categories have been inadverdently deleted dozens of times. Any way to prevent this completely so that categories don't need to be re-added?
