Stockfish Bug?

Hi everyone, I was just doing a tactic the other day and I noticed a strange error with Stockfish when I reviewed the answer in the analysis board after. Wondering why this happens and if this is a common problem or not.

From the FEN "2k5/8/1R1K4/Bp6/2b5/8/8/8 w - - 70 116", Stockfish gives the analysis #10, however, after Bc3 b4 Be5, there is the clear #3. This is forced. Leading me to believe that the evaluation of #10 is actually wrong.

Depth goes to 18, should be plenty to detect this. Am I missing something?

I don't know enough about "Local Stockfish" to advise.

Remember that it's a local engine, (Stockfish Javascript) which runs on your browser, and it's about 600 ELO weaker than the regular UCI version of Stockfish.
And that's because the Javascript version can only run in one core, can't use Hash tables and it has a lot of bugs.
The local analysis is ok for blunderchecking games and doing some light analysis, but if you want something more precise, download Stockfish UCI and run it with some chess software like Chessbase or Arena for example.

I see. Thanks for the info ChessElements.

After looking at your study DonOctavioDeFlores, I am even more confused, because originally I had the same position running on local stockfish in my browser, and it said mate in 10, but in your study stockfish doesn't even see a mate it just sees an analysis of +47.5! Very strange bug.
