Can n better determine the latest version of node when upstream downloads don't exist?

Problem

Node.js made some kind of mistake and published 18.20.5 without actually building the release files in the expected directory. See nodejs/node#55829. Any CI pipeline or tooling that uses n to download the latest 18.x version fails because of this. e.g.:

> if [ $DEV_MODE -eq 1 ]; then n --download engine && n exec engine yarn install; else n --download engine && n exec engine yarn install --production; fi
       found : /var/lib/jenkins/workspace/company_project_PR-2172/package.json
        read : ^18.13.0
      target : 18
  installing : node-v18.20.5
curl: (22) The requested URL returned error: 404 

  Error: download preflight failed for '18.20.5' (https://nodejs.org/dist/v18.20.5/node-v18.20.5-linux-x64.tar.xz)

Obivously this isn't an issue with n per-se ... but I'm wondering if there is something that could be done on the n side to not have errors like this affect users. I notice, for example, that https://nodejs.org/dist/latest-v18.x/ redirects/links to https://nodejs.org/dist/v18.20.4/, so maybe the way that n determines the latest version could be adjusted somehow?

Thanks!

Short Version

Is there a way to change n so that upstream issues like missing download files don't break users' pipelines?

Configuration Details

$ n --version
v9.2.3

$ command -v node
/Users/cmv/.n/bin/node

$ node -p process.platform
darwin

This may have been fixed already on the node side. Node.js just switched over to a new distribution method (using CloudFlare) within the last couple of weeks, and this might have been a teething problem with the new setup.

My usual expectation is that index.tab is the source of truth for what is available.

Thanks for node issue link. I have subscribed there to follow developments.
