Before opening this issue _please_ check we haven't already fixed it! Development always takes place in the Phaser `dev` branch. The easiest way to check is to read the [Dev Change Log](https://github.com/photonstorm/phaser/tree/dev#change-log).
API errors must include example code showing what happens, and why you don't believe this is the expected behavior. Issues posted without code take _far_ longer to get resolved, sometimes not ever.
If the issue is in a current version of Phaser, then you can use the [Phaser Sandbox](http://phaser.io/sandbox) to demonstrate it. Otherwise feel free to use another service, such as jsbin, or if you really must, codepen. If we can run it, and see the error, we can usually fix it.
