jQuery Masonry Spacing in Chrome

Love this theme!

But today I increased # of posts on the homepage from 10 to 15, and that change broke the spacing between posts (giant gaps between them!).

Not seeing this issue in Safari, but definitely in Chrome. Tried clearing cache and reducing posts on homepage back down to 10, which didn’t work. Also tried deactivating/re-activating the theme. Haven’t tried deleting/re-installing but may need to.

Wondered if there is an easier fix than that. Heard of this issue before?
