Bug: "Make Transform" node stops working after deleting connected variables

I am not sure I understand the question but you might have misunderstood what the “make transform” node is supposed to do. The make transform creates a transform, aka a set of a scale, a vector and a rotation, if you then want to set an actor to this transform you have to use the node “set transform”.

If this isn’t the answer please provide pictures of all your blueprints.
