You are correct, that is a bug! We found it at the last minute and frankly it was too complex to fix :-D I know that sounds dumb, but that was just how our algorithm worked for checking the solution.
As for the bankrupt wedge (or abyss wedge as we called it)--we didn't get enough time to implement features around it properly. For example, we were going to have artifacts that interacted with it, and there was a build where you wanted to ADD abyss wedges to your wheel to maximize the chances of hitting it. Something to come with the next version, I guess!
Thanks so much for playing!
