Error on render

[yaplas]

invariant.js:44 Uncaught Error: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's render method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner).

I dont know what is happening, but seems to be a problem when the router put and remove the component that host the MapChoropleth

@yaplas I also had this issue w/ two copies of Reacts being loaded. I solved this issue by deleting the duplicated react folder in node_modules/react-d3-map-core/node_modules/ in my proj dir. I followed the Two Reacts Won't be Friends section in this article to find where the duplicate react folder was. Hope this helps! 👍
