Custom events not working

Custom events not firing.
Lib version: 5.1.2

new Gumshoe('#services-nav-mobile a', {
    events: true,
    offset: function () {
      return stickerEl.getBoundingClientRect().height;
    }
  });

document.addEventListener('gumshoeActivate', function (event) {
    console.log(event.target);
  }. false);

Just tested this. I think your problem is the period in the second code block }. false. The following works for me.

document.addEventListener('gumshoeActivate', function (event) {
  console.log(event.target);
}, false);

Can't confirm it now because project is done already ant shipped, but very possible that this was the case.
