So I found one of the most random bugs I've ever come across.

So we have this file management system as part of the website, showing breadcrumbs to the current directory, with 'home' as the root of the path. This path is passed to the back end whenever the user navigates to a new directory etc.. The back end code then does a replace on 'home' with the actual directory path.

Ended up with a directory for a person called Homer. Guess what happened..
