Crash after file write creates an empty file

[EvilTurtleProductions]

I noticed something interesting: if our game crashes, after saving the player stats to a file and having finished this, the save file is empty.

The bit of code below is the stats saving, wrapping up some gameplay-related things and then clearing the procedurally generated level.
Sometimes the game crashes when clearing the level, which is way after the stats file has been saved. Yet the file is empty.

Stream* statsfilestream = FileSystem::WriteFile("playerstats.sav");
if (statsfilestream)
{
    System::Print("Saving player stats: " + std::to_string(playerstats_local.XP) + ", " + std::to_string(playerstats_local.level) + ", " + std::to_string(playerstats_local.money));
    statsfilestream->WriteInt(playerstats_local.XP);
    statsfilestream->WriteInt(playerstats_local.level);
    statsfilestream->WriteInt(playerstats_local.money);
    statsfilestream->WriteInt(playerstats_local.logs);
    statsfilestream->Release();
}

//SOME EXTRA BITS AND BOBS OF CODE HERE
//SUCH AS UPDATING INGAME MISSION SCREENS AND PLAYING VOICE ACTING SOUNDS


//clear level
ClearLevel();

The OS probably has a memory buffer that writes to the steam when a certain threshold size is reached, or when the file handle is closed. This would allow it to write a big block at once, instead of writing bytes in the same chunks you are writing them in.

If your game is crashing, you have bigger problems to sort out imo.

Haha, obviously the focus is on those
