This is still an issue, particularly frequent in large projects. And particularly annoying there because seemingly only invalidating caches can fix it and reindexing can take an enormous amount of time. Only for the issue to randomly appear again - maybe half an hour later, maybe a week later. I assume it's Cursive and not IDEA itself that's to blame here because I've never seen the issue outside of Clojure source files. https://clojurians.slack.com/archives/C0744GXCJ/p1553359490265100
