It looks like an NPP reviewer also noticed this, and we will want to fix it.

There is a script, updatePageTriageQueue.php that cleans up "old" items from the page triage queue. Its criteria for old is to look at the timestamp of when items were added to the queue, and remove items older than 30 days if:

// 1. the page is in the article namespace and has been reviewed, or
// 2. the page is not in main or draft namespaces or
// 3. the page is a redirect

The Nurgul Jones article matches criteria 1, as it was added to the pagetriage queue on September 3 2018. The Anastacia redirect matches criteria 3.

It would probably make more sense to remove items from the queue 30 days after the last triage action was performed, rather than 30 days after the day it was added to the queue. That could be a good feature request for future development.
