[SOLVED] LED Matrix and Code with a RNG stops working after a few minutes

I feel like memory leak is right on. The symptoms fit. I think the library might also be partial to blame. I did try running the code but it said 'neutral' was not delcared in this scope and highlighted...

void loop() {
  //looking loop
  rnd = random(4);
  rndDelay = random(700) + 250;
  rnd++;
  for (int i = 0; i < rnd; i++) {
    myLeds.clear();
    myLeds.setBrightness(1);
    myLeds.write(0, 0, neutral);

The final line of the myLeds.write(0, 0, neutral);
I don't have a good grasp on this library, or apparently proper declarations so that my loops can use the sprite objects. Is there a better library you or someone could suggest? Or even a simpler way to do the sprite drawings on the MAX?
