Crap, that was me. I have WheelMUD.Data as an external project in the Universe Manager Lite solution. I'm just about to jump in bed (couch), so I won't have time to deal with this until tomorrow.
I was trying to fix some references for FluentNHibernate. Go here
http://fluentnhibernate.org/ to get the version I was working with. It's the 1.0 RTM binaries in the zip download. There's a weird version conflict with the SQLite driver assembly. That's where I got stuck.
