Stockfish 19 - does it make mistakes in drawn endgames?

After running engine shootout games on drawn positions, it happened a few times that SF19 is showing 0.00 centipawn evaluation for many plies and then suddenly makes a losing error. Really strange pattern - and it appeared in SF18 as well. On the next ply, engine immediately recognises the error and shows mate in x. I believe this is a bug. Attaching screenshot and pgn. Interestingly, the same error appeared when I loaded the pgn into LC and switched on continuous analysis (also SF19 now).

Has anyone else noticed these patterns? It is kind of annoying as it invalidates an entire shootout analysis (showing one side winning instead of a draw as a result).

Thanks for your input!

Here the enriched pgn for reference. Error is in move 123 for Black.

I thought stockfish analysis on Lichess also used syzygy tablebase and the Lichess one that has partially solved 8 pieces endgame

Not sure it did when I tried replaying the pgn online with engine switched on. Either way, the engine seems to make a losing error and it should be able to avoid it with or without endgame bases.

"it should be able to avoid it with or without endgame bases"

• With the table base yes, without only if within the calculation horizon.
