In certain Rails versions there's been Marshal serialization bugs and it's pretty tricky to test those because the new Rails version can't output the old Marshal structure.
So it can take a long time to reproduce, but now you can grab a dump from production and put it in a SQL file directly.
This also moves the cases folder into a test/ environment folder since that's what I'm recommending in the README.
