CGE2で生成したAnimator Controllerを結合しようとするとIndexOutOfRangeExceptionがでる

[Narazaka]

Combo Gesture Expressions 2.0 系で作ったAnimator ControllerをAnimatorControllerCombinerで結合しようとするとIndexOutOfRangeExceptionがでます。
デフォルトステートが見つからない？っぽいエラーに思いますが詳細分からずでした。
なおCGE2で作ったAnimator Controllerのこけているレイヤーは謎矢印があったりややトリッキーにも見えます。

サンプルとしてこのanimator controllerでこけます
