I never noticed this problem before until I started playing with the size of the box.
[bfslider type="news" imagesize="normal" numposts="5" numwords="60" height="355" maximageheight="300" bgcolor="#666" color="#fff" numeric="false" auto="true" animation="slide" buttons="style2" pause="5000"]
That is the shortcode I use, which causes the problem shown in the picture below.
However, before, when I had height="300" and maximageheight="245", everythign lined up perfectly. Now, one of my posts doesn't line up anymore (all the other posts still line up correctly).
What caused this problem? All my feature images are 848 x 441 or 848 x 442, so they should all be big enough for the content slider's smaller size.
