I think there are a few issues here. Sometimes the sim can’t get real world data, or gets data that doesn’t match the real world. Sometimes the sim gives wildly different weather a few minutes a part.
I was flying into Rome, when I first got ATIS it reports wind straight down the runway at 54(!) knots. Cleared for approach, ATC calls 10kt direct left cross. Cleared for final, now ATC says 8kt direct right cross. This was all from in-game sources, and I was in the CJ4, so the time wasn’t that far apart.
