Blog view displays inconsistently

[bengolden]

https://www.cultivatelabs.com/blog is displaying fairly differently at different times, sometimes loading blog post images and sometimes not (also some formatting differences). For the most part, images load when I click the BLOG link on the site, but usually don't when I enter the url.

Html snippets:

<div class="post-list post-padding">
  <div id="blog_post_75" class="blog-post">

<div class="post-list post-padding">
  <div class="blog_post-list">

My guess is there are two different partials been loaded in different cases, but I'm not sure why. The url is the same in both cases.
