Domain Not Mapping After 3.0.8 Update

I've been troubleshooting this issue since updating to Domain Mapping 3.0.8 earlier today with no luck.

We had the domain ourfreedomtour.com successfully mapped to wayneb.agreda.com and working fine all week. After updating the plugin, the custom domain now shows the default page from the registrar.

The domain reneagredano.com is successfully mapped to rene.agreda.com and is still functioning fine!

Both custom domains are registered via 1and1. Both have identical DNS settings at the registrar pointing to our nameservers. DNS status for both at the registrar show as ready. Both are parked at agreda.com.

So in short, both custom domains were working, both have identical settings, but now one is not working.

Any suggestions for getting it working are greatly appreciated. Thanks in advance for any help.
