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

When I fast change the page on my website, sometimes I get this error on browser console:

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. Carousel@http://localhost:3000/static/js/vendors~main.chunk.js:56014:20
div
Container@http://localhost:3000/static/js/vendors~main.chunk.js:79174:18
.....

The part of code reported by console is this:

function Carousel(props) {
    var _this;

    _classCallCheck(this, Carousel);

I know it's not a big deal but it's a bit annoying.
Or I wrong something in the implementation?

Thank you for your job.

Thanks @daniteohotmail .
Are you using enableAutoPlay prop?

I couldn't reproduce it but i think i know why it's happening. I released a beta version with a fix, can you please try installing version 0.11.5-beta.1 and let me know if the problem is fixed?

[daniteohotmail]

Hi, enableAutoPlay is false.
I install the 0.11.5-beta.1 version but the problem is still happening.
Can I do any other tests to help you?

Hmm interesting. Well, a reproducible example can help a lot.

Hi (I'm the same person with my new account).
I create this sandbox for reproduce it.

Click two times the button and in console will appear the error.

@sag1v Hi! I tested with the 0.11.5-beta.2 version but the error still happening...

@danielefontana95 Sorry, i published a wrong beta version. Can you try 0.11.5-beta.3 please?

I tested it with your sandbox example and it seems fine.

[danielefontana95]

Yesssss! It seems to be working correctly now.
Thank you, very great job!
