I am assuming it would be extremely difficult to add a feature which highlights the segment of a prompt that the AI can't work with. Tangent, I have notice that prompts that didn't work when I first tried them work later after some setup. For example, at first it would not let me say a creature tried to absorb me. After I wrote a prompt where the creature grabbed a hold of me, the AI was fine with the same creature trying to absorb me.
