Here's what I did:

1. On zw.goodinternet.org, I created a redirect from /en/sandbox/your-health/ pointing to a page which was located at /en/sandbox/your-health/
2. I changed the stub so that the page was located at /en/sandbox/your-health2
3. The redirect successfully pointed /en/sandbox/your-health2/
4. I then changed the page stub to /en/sandbox/your-health/
5. The redirect continues to point to /en/sandbox/your-health2/
6. Even after deleting the redirect, /en/sandbox/your-health/ redirects to /en/sandbox/your-health2/

I tried changing the redirect to point to another page, tried changing the Page stub to multiple other settings, the Redirect always seems to point to /en/sandbox/your-health2/

Desired behavior:

Changes to a Redirect should be successful.

If they are very delayed (eg 30 mins?) that should be clear to the Admin. If this delay is the case, right now it's difficult to understand because new Redirects are implemented immediately.
