When doing yo reveal:slide "4.DAG" --markdown, it fails with the following error:

TypeError: Cannot read property 'push' of undefined

If I change the command to yo reveal:slide "DAG" --markdown, it works. Seems like the 4. in the title blows things up. Weirdly enough, I was unable to reproduce this in a test, so I can't submit a PR with neither a fix nor a failing test. Sorry 😕 .

Ideas what might be causing this?
