After switching states the InversePointProxy for the p2 world physics is broken, this is because the actual array the proxy refers to is no longer used by the p2 world.

On reset the world reruns the ctor which creates a new array for the world gravity. The InversePointProxy in Phaser's P2.World still refers to the old one so you have to access the world gravity manually instead of using the point proxy.

When you change State the P2 Physics world is no longer fully cleared…

…. All of the bodies, springs, fixtures, materials and constraints are removed - but config settings such as gravity, restitution, the contact solver, etc are all retained. The P2.World object is only created the very first time you call Physics.startSystem. Every subsequent call hits P2.World.reset instead (#1292)

This should now be fixed in dev. Test example here: phaserjs/phaser-ce-examples@971f0c6
