Problem with stockfish level 8 in antichess

Dear all,

I am just making this topic to signal that Stockfish level 8 in antichess has started to make a strange mistake.
Indeed in two games as black it has played a losing move in move 3 (3.. Qxd7).
The strange thing is that at first it does not recognize the losing move for black but it does after one move. It only recognizes it in the analysis while increasing the depth.

Here are the two games I am referring to:




Also I hope that this topic belongs to the good section.

Best regards,
Nico

@TheBigNico well done on your wins

@howchessYT Aha thanks but I have nothing to be proud of it's forced mate after 3 moves ^^
My point was that Sf 8 should not play this, and that it should detect that it is a losing sequence. Moreover, it never played it before

Here is a study that proves that it is a losing move:

I can not reproduce this when using Stockfish on the command line, neither with the last release nor with the current development version, so I have no idea what could cause these blunders. Already at depth 1 and also for all other depths (tested up to depth 25) it never shows Qxd7 as the best move, but always one of Bxd7, Nxd7, and Kxd7.
