Sinking through the floor

I have a project all setup and working with Windows MR, however as you move around the scenes the character slowly sinks through the floor.

I think it may be related to sloping floors. Anyone come across this.

Using 2017.2.0p1-MRTP4 with HoloToolkit-Unity-2017.2.1.0.unitypackage.

MixedRealityCameraParent on which I have a child component that has a capsule collider and a rigidbody

Ignore me, fixed in the latest release of MixedRealityToolkit-Unity
