1.9.3.1 Upgrade, now no Out of Stock variations shown in configurable products

[GTLTD]

After upgrading to 1.9.3.1, out of stock variations are not shown within configurable products. It was working prior. Has anyone else had this problem, or does anyone know how to fix it? Is this a Magento bug?

Thanks in advance :-)

It was an issue with one of our extensions, which has since been updated.
