When I click the "roll clockwise" button, the animal rolls counter-clockwise. When I click it again, the Done button is activated, with the animal in the wrong position. The "roll counter-clockwise" arrow also spins the animal the wrong way. The page behind the verification is black, not greyed out as normal.
I'm working on a Mac 10.13 VM under Windows 10, with Safari.
ETA: Working fine after letting the VM update the OS. I wonder what that was all about?!
