Crash when loading Anim BP after undoing and saving "Use Shared Rule" in state machine

It seems that undo-ing the transaction in UAnimStateTransitionNode::UseSharedRules, leaves the outer graph (UAnimationStateMachineGraph) with a nullptr entry in its SubGraphs array (instead of the TransitionGraph?). Which is not guarded/checked for when reloading the asset, and asserts/crashes at UEdGraph::GetAllChildrenGraphs
