Multisite w/ Domain Mapping & Dedicated IP – Godaddy

I’m trying to get Domain Mapping setup for my multisite so blog users can use their own domains.

It all seems to be working fine except for a single fatal flaw.

I’m trying to map https://www.thoughtsofthemasses.com/fjrichman to https://destruir.net/

I took all the steps added the IP to the domain to point it, mapped the domain to the site with a plugin. But now that whole blog maps to the main blog. If I remove the mapping /fjrichman becomes usable, but with the mapping enabled it redirects to the main blog.
