Problems serving mdbook

[Tealk]

Problem

When I use mdbook serve, I get the following errors.
The first time I click on a navigation link, I get to the correct page. http://localhost:3000/material/waffen/index.html
The second time I click, it duplicates the path http://localhost:3000/material/waffen/material/waffen/index.html
The third time, it is correct again, and so on.

Furthermore, since the last update, the menu items no longer work when expanded.

Here is an online version of the problem. https://bak.butterfly-aspect.de/

I think you'll likely need to update the index.hbs file in the theme. It has some controls for navigation, and they changed in the latest version.

Yes well I should have realized, sorry for the circumstances.

No worries. It would be nice to figure out a better way to handle updating it. I'm not sure what that would look like, but perhaps it could at least warn you about it. I should also probably make it more prominent in the release notes.

I could also have seen in the commits that the index.hbs was changed, I just hadn't thought about it because it is so rarely changed 😓
But a "template has been adjusted" in the changelog would also be a good hint I think.
