Clear story.
I'm not an expert but if we , as a community , advised T to make a crown with 60 teeth and afterwards some people realise we all made a mistake then i think it would be fair to compensate T on that loss ( for instance by buying a t48 crown).
It's not fair to benifit from a great price thats offered and when the [censored] hits the fan to sit still or even ask for a refund on a mistake we ALL made.
You win some and you loose some but 10K is a bit too much.
