Reporting Puzzles

How do you report puzzles? I ask because this puzzle is incorrect: lichess.org/training/61720
The puzzle says that Be3 is wrong, but it in fact leads to mate! To respond to Be3 Stockfish gives Kxc4 Rd5 and then suddenly it's mate in 8(I'm pretty sure a mate is more valuable than some other advantage)! The other alternative to Kc4 is Nd4, which is also winning for white and no other options are doable. I think Be3 is better than Rd5 (the answer), or that they are both equal. For more info, check the game's chat: <iframe src="lichess.org/embed/HFJPjIdm#55?theme=auto&bg=auto"

Btw, this is not the puzzle, it's the actual game where the puzzle was missed.

I just came from that puzzle and I want to reiterate what OP said- there is more than one solution. Still interesting, tho!

Both Qxf8 and Rxf8 are clearly winning on stockfish's account, but Qx isn't accepted.
Rx is better in this case, but Qxf8 is still +3 at depth 30, so clearly better unless there is something insanely deep

How has this question got an answer in the FAQ??????????????? This is a perfectly valid forum.

Yeah, how can we report an incorrect puzzle?!
I cannot find anything in the F.A.Q

Maybe someone should just check the F.A.Q.

Nope. Can't see anything. Maybe someone else with better eyes should look.

I don't know whether the answer is in the FAQ, but if you want support you've come to the wrong place and need to try the contact page.
