subcontent-wrapper outside of content-wrapper

Hi there, I updated my comicpress from 4.2 to 4.3 and while it looks fine on Chrome, on FF all custom pages, the subcontent-wrapper becomes 2px wide and pushes itself off a bit beyond the right side of the content-wrapper completely. I’ve commented out all of my child-page css that I had created to make costum widths for the previous version, but it did not fix anything. I haven’t been able to fix the issue with child-css yet, but I’m probably going to keep trying.

I do not know if others are having this issue or not, but would be interested in finding out.

Here is a link to the home page where it looks fine: http://rachelboyes.com/bounty/

Any info or theories from anyone would be appreciated.
