Moved domain to another network, old site keeps redirecting

I've moved a mapped domain to a new network, while deactivating the mapping in the old one. However, when trying to enter the "old" site (without the mapped domain) it redirects to the new network site.

I just checked on the mySQL tables and there's no registry for the domain mapping there (nor in the plugin settings).

What should I do to be able to get into this site? :disappointed:
