Sauce: https://community.magento.com/t5/Technical-Issues/Cookies-frontend-cid-is-never-renewed-compared-to-frontend-one/td-p/41077

The core code seems to have forgotten to include the logic to renew the frontend_cid cookie.
 
I have contacted Magento support regarding this and they provided me a patch - SUPEE-7136, however I'm not seeing it published online anywhere...
 
The issue lies in this file:
app/code/core/Mage/Core/Model/Session/Abstract/Varien.php
 
What the patch does is replace this:
