Hey @shiena. Thanks for another pull request.

Can you do me a favor? Can you create an issue for the problem you are fixing here?

It's a formality we have that helps our reporting for release notes.
We don't create issues only when refactoring or code cleanup, but if it is a bug fix or enhancement we need an issue.

@StanleyGoldman OK. I posted #206 !
