When I had a DIV with pagination below block grid container, and I used "text-center" text align class, my pagination links sometimes aligned too much to the right and not in center.

This was because the negative margin of last row block grid items somehow collapsed into the pagination div and affected text align calculation. Despite the fact that block grid container has "clearfix".

To get rid of this problem, I had to wrap blockgrid into another div and give it clearfix class as well.

This was not working with the current version of bootstrap and seemed to be a similar error read here:

wrapping the $nth-equation in parentheses seemed to fix the issue for me:
$nth-equation: (#{$per-row}n) + '+' +1;

Libsass will not compile the CSS correctly.

Use $nth-equation : (#{$per-row}n) + '+' + 1 instead of $nth-equation: #{$per-row}n+'+'+1; as mheywood90 pointed out.
