Can't call setState (or forceUpdate) on an unmounted component

Hi

I created a FluidNavigator and included it in a DrawerNavigator like so.

const ReceiptsNavigator = FluidNavigator({
  AllReceiptsScene: { screen: AllReceiptsScene },
  ReceiptScene: { screen: ReceiptScene },
});

const screens = {
    Home: {
        screen: HomeNavigator,
    },
    Receipts: {
      screen: ReceiptsNavigator
    },
/*etc*/
}
const RootNavigator = createDrawerNavigator(screens, {
 /*some options*/
})

Everything works well within the FluidNavigator but sometimes when I navigate out of it I get this error

C:\git\HausMart\minibar-client-mobile\node_modules\react-native\Libraries\Core\ExceptionsManager.js:71 Warning: Can't call setState (or forceUpdate) 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.

Any ideas? 😃

I see that the PR is closed, has this been added to a release? Because I still get this error.

@Dagurmart A fix should be available in pr #107.
