So after some more testing I've run into a roadblock.
I can get the story to build but something gets corrupted. When I close the editor and try to open the mod again it crashes. It will work fine until you close it though.
I'm pretty sure this is caused by the file (which is generated during building) called story.div.osi. I'm not sure yet why it causes the crash but when I delete the file my mod loads. I have to rebuild the story but it works.
