Stockfish when running lila locally gives wrong eval

[johndoknjas]

Possibly related to #17772?

Exact URL of where the bug happened

Analysis board with fen 8/1PK5/8/8/8/8/8/4q1k1 w - - 0 1

Steps to reproduce the bug

1. Run lila locally
2. Set up 8/1PK5/8/8/8/8/8/4q1k1 w - - 0 1
3. Turn on Stockfish

Even after letting the engine get to depth 34, for me it evaluates b8=R as only -0.6. While on the prod site, Stockfish very quickly gives an eval of more than -2.

What did you expect to happen?

A much bigger eval

What happened instead?

It evaluates as Black only having a slight advantage. Even if stockfish is slower on my local environment, -0.6 at depth 34 is really strange.

i agree with 0. the queen trade is instantaneous.

never mind, i see you're promoting to rook.

that's what i see with both Stockfish webassemblies. try relaunching your browser.

the web results are the same as the native binary (below). interesting that cp really starts soaring in the late 30s.
