Forum:Changes in Templates not showing in Category

I've recently altered a template (this one) so that instead of just adding the article (e.g. Spell Rebound) to the "Spell" category it adds it to "Class Spell" category (e.g. Feca Spell). However, while the articles correctly show and link to their new category.. the old categories still show the article, and the new category shows up as empty.

Is there some sort of delay between a template being changed, and the categories recognising the change? Or is there something I need to "nudge" so that the changes are recognised?

I have found one "solution" which is to manually add the new category to each article (which puts that article in the right category), and then delete the addition afterward (it doesn't revert back to the "incorrect state").

Any help is appreciated --Defunc7 16:53, February 19, 2010 (UTC)
