  Doesn't seem like a bug indicative of being beta. The bug could obviously be fixed by looping back to 0, but the correctness is not the important part. Though, reporting such an issue does not seem to be possible, hmm :(

  Nice find! One of the pages has an exercise where you need to fix this bug.
