The Wikia Gaming Calendar seems to show up randomly depending on which wiki you look at even if it is in the Gaming category. I see it here on w:c:swtor:Special:WikiActivity, but not here on w:c:halo:Special:WikiActivity. Why?

Info like "This calendar does not display on every wiki." doesn't help at all.
