Full build failing

[LiamConnors]

Full build failing:

Git diff step failing with:

On branch fix-broken-links-2
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        output.tgz
        output/

nothing added to commit but untracked files present (use "git add" to track)

Are you OK merging #4618 despite the broken build?
