I am facing the same issue with way smaller case classes that are, however, deeply nested (like 5-6 levels deep). Gradually commenting some of the fields out, then compiling, and finally reenabling commented lines to compile again will eventually lead to a working build. But a clean build always fails with the missing Encoder/Decoder error. This issue keeps me from actually using circe.

FYI, the example in the gist above is fine with the current snapshot of argonaut-shapeless. There has to be a way to have this working here...
