I can reproduce this issue quite simply using the “Quick Start” project.

Steps to reproduce:

- Follow the steps to get a working Hugo site outlined in the Quick Start
- Create a number of pages and add them to the main menu by adding `menu: ["main"]` to the front matter
- Edit the `themes/ananke/layouts/partials/site-navigation.html` to add the following code directly after the matching block that renders the menu in a forwards direction. (Note the `.Reverse` added to the menu array)

```auto
        <ul class="pl0 mr3">
          {{ range .Site.Menus.main.Reverse }}
          <li class="list f5 f4-ns fw4 dib pr3">
            <a class="hover-white no-underline white-90" href="{{ .URL }}" title="{{ .Name }} page">
              {{ .Name }}
            </a>
          </li>
          {{ end }}
        </ul>

```

EXPECTED: the list of pages followed by the list of pages in reverse displayed consistenty on each of the pages as you click through them.

ACTUAL: Indeterminate ordering of the ranges as you click through the pages.

My guess is that the pages are being rendered in parallel and there is a range cursor that’s being trampled by different threads… or I’m missing something obvious and doing something wrong.

I’ll test it out if you wrap your test project in a repo and share it. 🙂

The results prior to `Reverse` are not deterministic, and `Reverse` doesn’t cause a sort to occur [[1](https://github.com/gohugoio/hugo/blob/ae5a45be6f0ee4d5c52b38fd28b22b55d9cd7b2d/hugolib/menu.go#L205-L212)]. You should sort prior to reversing. Try this:

```auto
{{ range .Site.Menus.main.Sort.Reverse }}

```
