Exactly, and that’s why I used a Child Theme. Moreover, there does not appear to be any changes in the theme code, but somehow it’s getting overwritten and not appearing as it is written in the child theme since the update.
I too lost design content once I upgraded to 4.2.2. VERY frustrating. The fonts changed back to the original theme even though I am using a Child Theme and the Custom CSS show the names of the fonts I switched to. Is there a way to revert back so I don’t have to redesign my entire site. Extremely frustrated and disappointed.
