RansomTime's interpretation is correct - to avoid causing spikes in server load, the software uses a job queue to work through these kinds of page updates (and this is not specific to Wikia). What can happen is that the job queue can get quite long, which can slow down updates - I will check with the technical team to see if it's currently peaking (and see about getting it reduced, if necessary).

452 is also correct that making an edit to an affected article will cause an immediate update, essentially jumping that page to the front of the queue.
