I updated to 3.16 as well and have the same issue. The arrows to scroll the carousels are placed underneath the carousel and not overlayed. When I went to @djvegas87http://www.cosmeto.tn website, his does the same as well. Cleared caches, used diff browsers etc.
I think that this is a serious problem for just adding a custom css… please forward it to Ed, may be you will need to update the theme again before a lot of websites using the theme do this update…
