Issue: Category's aren't populated when wiki entry is saved with a new category

When I add or edit a wiki entry and add a CATEGORY bbcode, and then I go to that category page, the entry does not show. It's only when I go BACK into the the wiki entry that the entry will now show up on the Category page.

It's very confusing to save a wiki entry, see the finished product, immediately click to go to the category page and not see the entry just created. The category list should be updated when the wiki entry is saved, not updated when the wiki entry is accessed.
