Has anyone else seen these margwa hearts showing up around the map? I've found 4 different locations where margwa hearts appear seemingly after killing the 2nd and on margwas. Obviously the first one drops on the ground for the WW. From then on I noticed them popping up around the map. ( wont let me upload my pics. ) Also, every now and then my screen will like . . . tremble. It's hard to describe but it definitely happens. I re-watch it in theater and can't figure out why this happens. Anybody else experience this?
