Update Breaks Category Widget

I was within hours of launching a major site rebranding (in the middle of doing my redirects which I now I have to remove until this problem is fixed). I saw an update for WooCommerce come through (2.0.15), so I decided to run the update before the launch.

Immediately after running this update, my category widget on the blog stopped working. It says there are no categories to display although the categories still exist on the back-end.

I see I’m not the only person having this issue. Any solutions or easy way to revert? I’ve made no other changes since that upgrade, so it’s definitely tied to that.
