Unexpected error?

When I pick the girl i chose as my starter and try to save it, it says there was an unexpected error. I've tried it multiple times, and it always comes out as an error. Please help?

Start by reproducing the reported flow: choose a girl as the starter and try to save it. Inspect the resulting error and relevant application logs to identify where the failure occurs. Done means the starter can be saved successfully and the error no longer occurs.
