Yep this I got, the issue was that when I create a new node (right click the blueprint editor, “New… Reactive State Machine” and then change the Machine Class to the RSM_Input (or whatever RSM I’ve created), the FSM node from that node is not of RSM_Input type, instead it is of Reactive State Machine type, regardless of if I compile or not. I literally just fixed it by restarting the editor but I suspect that that is a bug?
