Yeah, I noticed this too. I think it has to do with Rails rather than Engines... might even be a bug. I noticed in the changelog that the controller instance variable inside sweepers is set to nil "between requests"... whatever that means. I figure that's what's causing the error, but I haven't figured out how to fix it or even looked into whether its a reported bug. I just have my sweepers turned off for now. : (
Let me know if you learn anything about this.
