Can't perform a React state update on an unmounted component

[ako977]

This seems to usually occur on state change (usually during development when a hot reload occurs on the watch)

index.js:1437 Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.
