Just to elaborate on this issue, I’m getting it in another situation too, attached are the two steps for reproducing it on my end.
Setting the start to a new node that isn’t attached to anything causes some to black out.
Edit: I’ve actually encountered this with a 2 state looping FSM that I added to the example shown above, and when CTRL-Z undoing and CTRL-Y redoing something, the two nodes got mashed and turned black, even without setting anything to Start. (Attached are Example 5 and 6)
