I've done this with two species now, and the same result happened. The only differences are the use of the setConsequenceTrait vrs the one that gives you all the planet sculpting tools.
Basically, once I have the wormhole key, I try to enter a black hole. On leaving, I can't actually leave the presence of the black hole, nor can I access the menu. I am using v 1.1 and am not using the trainer.
