Clojurians Log v2

Anyone here particularly adept at figwheel? Built a Reagent app from the default Reagent lein template and deployed to heroku (http://www.archetyp.io) but even in prod there’s a brief “ClojureScript has not been compiled! please run lein figwheel” which displays and then disappears after compile. We don’t use :requires outside of a namespace declaration (as per one post on SO) and I think our :builds :externs are all correct. Any ideas or pointers in troubleshooting? Our project.clj is here https://gist.github.com/ekhall/d852a29bd4acce0256975ca6af910bdd
