Interestingly, due to the way I built my wedge, I actually had to rotate the Y axis by -90 in order to get it facing up. If I cut its scale to .5 for each, I essentially got a very small wedged cube, so I altered its dimensions by halving each of those numbers. Got the desired results, just in a different way.
Exactly the same happened to me 
nice! hope this doesn’t happen to me, I’m about to try the exercise
