When I cider-jack-in outside of a project, my cider REPL doesn't output any evaluation. I type (+ 2 2) and hit enter, my cursor goes to a newline, nothing is output. I hit enter again, I get a fresh prompt. I put a debug-on-entry in the callbacks, cider-repl-emit-result, and I never hit that debug. It's like the client is sending the evaluation to nowhere, never getting a response. I'm stumped on troubleshooting. Any ideas?

cider-jack-in inside a project works fine. I've tried cider-jack-in-default as 'lein and 'clj to same [lack of] effect.
