When navigating directly to a sub-category page via URL on Firefox or Edge (doesn’t seem to impact Chrome), it results in a broken page. Example URL: http://talk.readyatdawn.com/c/deformers/techsupport
However, when navigating to that same page from the Category page first, it seems to work fine. Example URL: http://talk.readyatdawn.com/c/deformers (now click on “Tech Support” and view the page).
Not sure if this is something I’ve screwed up in CSS (if it is, any pointers on how to fix this would be super helpful).
