Hi Ciaran,
I'm using Skylar and one of my webpages. On one of the pages, I'm using the masonry category blog (pls. see the link). Today I found, it looks like a mess. Some Intro-Pictures are next to the Intro-Text, others are above. And pictures are randomly bigger or smaler. I did not frequently check this page, but I saw it when I add a new article today. I could be, that this exist already since the latest Joomla Updates. Any thoughts?
