I just bought a new laptop and for some reason i can't stalk either with Myers or Ghostface. I can press M2 and do the stalking action, but the bar would just not fill up and the survivors aren't highlighted in white... How can i fix this? Here's a video of how it feels like: https://www.youtube.com/watch?v=UtdWa6lDN8w&feature=youtu.be
