@ted,

Actually, you can feel free to disregard this. I ultimately traced the issue back to a plugin that hooked into the `UserScoreSerializer` that implemented its own narrow `.select()` statement. It wasn’t apparent initially because there was no backtrace provided in `/logs` for the `MissingAttributeError`. Only after digging through and making the call manually through rails to get a full stack trace was I able to pinpoint the errant plugin.

Thanks, and sorry for the false alarm!
