All charms who do not update regularly are moved to the "inactive" page of SC. Once they update, they are put back in the main pages.
Here's the link to the inactive charms:

You can get to it also, by visiting the SC main page. On the top next to the SC1, SC2, SC3, SC4 links is an "inactive" link that takes you to the inactive charms.
