After updating my mega menu top level items have stopped being clickable. This is also affecting 2 level items that have 3 level items attached. (such as on the Programs menu item) All main menu items that do not have child items are not affected.

My navigation addon section menus at the bottoms of the pages are not effected and working as expected so I am pretty sure this is an issue isolated to the Mega Menu.

I am clueless on how to trouble shoot or fix this. Help with this would be greatly appriciated.
