Lastest Alpha has TransformNode Error

Just an FYI to whoever

I get this error for my components using AbstractMesh:

Assets/[App]/babylon.scenecomponents.ts(469,21): error TS2322: Type 'TransformNode' is not assignable to type 'AbstractMesh'.
  Property '_facetPositions' is missing in type 'TransformNode'.

Assets/[App]/babylon.scenecomponents.ts(490,17): error TS2322: Type 'TransformNode' is not assignable to type 'AbstractMesh'.

I dont reference any TransformNode so it MUST be some internal Change to the AbstractMesh class
