Please provide any additional information below.
I have two account so I was married when I attempted this. I hope it helps. Also, I encountered another error with /gods info where I would get a "There is no god with that name" message, despite the fact I had a god. However that bug went away when I ran the server with ONLY the gods plugin so I'm assuming it has something to do with incompatibility
