Coding Help Exception while trying to add a Buff to the game.

[SomeoneEls]

The idea is that a buff will be added to the game periodically to the bpm of a song. Here is the code for the method itself, but I highlighted with //problem here to show where the problem area is. This is supposed to be run by a thread.

public void OSTBPM(object o)
{
string track = "";
bool running = false;
Action<object> wait = (j) =>
{
string t = track;
Game1.showRedMessage("Great!",false);
for(int tim = 0; tim< 50; tim++)
{
if(t != track)
{
break;
}
Thread.Sleep(1);
}
running = false;
};


buffDataMusic = new BuffAttributesData();
buffDataMusic.AttackMultiplier = 3;
buffDataMusic.LuckLevel = 3;

buffEffectsMusic = new BuffEffects(buffDataMusic);

int val = 0;
while (true)
{
try
{
track = Game1.getMusicTrackName();

while (Game1.getMusicTrackName() != null && BPM.TryGetValue(Game1.getMusicTrackName(), out val) && Game1.player != null && track == Game1.getMusicTrackName())
{
val /= 2;
for(int tim = 0; tim< val-75; tim++)
{
Thread.Sleep(1);
if(Game1.getMusicTrackName() != track)
{
break;
}

}
if(Game1.getMusicTrackName() == track)
{


for(int tim = 0; tim< 150; tim++)
{

// Problem here.
musicAttack = new Buff("1337", "none", "none", 150, null, 20, buffEffectsMusic, false, "MusicBuff", "Only active now")

Game1.player.applyBuff(musicAttack);


if (Game1.getMusicTrackName() != track)
{
break;
}
if(Helper.Input.IsDown(SButton.MouseLeft) && running == false)
{

running = true;
new Thread(new ParameterizedThreadStart(wait)).Start();
}

Thread.Sleep(1);
}


}


}
}
catch (Exception e)
{
while(!(Game1.getMusicTrackName() != null && BPM.TryGetValue(Game1.getMusicTrackName(), out val) && Game1.player != null))
{
Thread.Sleep(1);
//Console.WriteLine("fail");
}
}
}
}

The problem itself is an exception which is here. It happens almost randomly.

For some reason, musicAttack has to be defined in the for loop it in or the game thinks that the milliseconds duration is null. I'm adding a new key that isn't in the buffs file, so this might be an issue?
Ill see if I can add it, but for now, any help would be great :D

I tried changing the id to an existing one, but the exception still happens.

Learned that this causes a crash when trying to play the lewis community center cutscene at the start of the game.
