Bug in a puzzle

lishogi.org/training/mateIn3/mVXsq

This is a tsume where you play with one side, the only side whose pieces I can move, and the other side has the mate in 3 I needed to find.

While also thinking about it, why not create a forum solely for mistakes in puzzles?
Lidraughts has such a forum and it reduces the number of different forums with 'Mistake in puzzle' complaints.

For mistakes in puzzles, you can do either of the following:

1. Report them in the Feedback Forum.
2. Downvote the puzzle.
3. Report them in lishogi’s official discord.

Thanks for clarifying what I should do. @YoBot_v2
