multi domain plugin add site errors

I am having the same issue as in the following thread:

If I disable the multi domain plugin the issue goes away. I am running the current version from WPMUDEV. I assume that since the referenced thread was from November of 2013 that the beta code talked about has made it into the release code?

Any thoughts or ideas would be appreciated as this is a huge feature for my site that I am getting ready to launch next week.
