When setting Nova (Grey Goo Armor) to Double Goo appearance there is no available bust.
Additionally some interactions with Grey Goo (and I think any inventory interactable) leave no options on the screen and the inability to move, I'm not able to reliably recreate what I'm doing to cause this though. A temp fix is to open your characters appearance screen as this always remains available and then clicking the back button which wakes up the game and allows normal interactions.
