Hi, Changes to app state *can* cause components to be unmounted. Imagine a component that renders another component, if a boolean value in the app state is true, otherwise it renders and empty div. When the boolean changes from true to false and the component is re-rendered, the subcomponent will be unmounted.
However, if the subcomponent should be re-rendered in both cases, it should not be unmounted. Thinking about it, you're probably mistakenly using a different react-key between the renders. This will cause a new component to be mounted as it is not treated as a continuation of the previous component.
