Bonus puzzle identical to today's 6x6 Difficult
Strangely, the bonus puzzle I just unlocked is identical to today's 6x6 Difficult – including the candidate numbers I "pencilled in" while solving one of them
(Just in case this has anything to do with the bug: I am not entirely sure if I solved the newly-unlocked bonus puzzle first in order to solve the supposedly harder 6x6 Difficult later or if I solved all three regular 6x6s before turning to the bonus puzzle. Both of the puzzles appear with the note saying that I've already solved this puzzle. The word "Difficult" has the green background indicating a solved puzzle but the words "Bonus puzzle" haven't.)
