When setting the burst count using the rand() function, the burst behaves wierdly, or random, too random. Sometimes the children are not spread out evenly, sometimes it's like the last childs is still playing. Compare this to when you set either count to, 2, 3, 4, 5 or 6 directly compared to 'rand(2, 6)'.

Example:

const example = new mojs.Burst({
  parent: '#example',
  x: 'rand(-50, 50)',
  y: 'rand(-50, 50)',
  count: 'rand(2, 6)'
});

document.addEventListener( 'click', function (e) {
  example.generate().replay();
});
