Again, you don't valgrind a whole game. You valgrind your unit tests. Even in 2004 when this game was released, and even in the game industry, unit testing was a routine thing. And this particular bug was in code very amenable to lightweight unit testing.
That would be assuming they knew there was a bug in that particular part of the code, which they probably didn't, until Windows 11 24H2. And unfortunately Valgrind doesn't work on windows.
