Color Paper Theme Breaks Admin Bar

I noticed on two of our member sites, using the same "Color Paper" theme, that the drop-down menus in the WordPress Admin Bar do not function. Neither the Custom Admin Menu nor "My Sites" show the menu options when rolling over them.

We installed the Color Paper theme as part of Farms 133 Theme pack and have the most recent version. We are also running the Custom Admin Bar plugin v.1.3.2.

FYI: The Firefox Console reports the following for /admin-bar.min.js when loading the site:
TypeError: this.on is not a function

Could someone please try to replicate this and provide feedback?

Thanks!
