I am working on a Next.js 13.3 project using the appDir approach.
I created a not-found file for handling 404 errors that gets displayed correctly, however, when I am on the not-found page links to other pages (like /subpage) do not work, they change the URL in the browser but the correct page is not loaded (when I click on refresh afterwards, the correct page appears).
I think this might have to do with client side rendering or link prefetch that is somehow broken. Any ideas what the problem can be?
