I have this bizarre issue with Walking Dead in the last episode where I had to come to a water tower across a highway and Clem asks me to cover myself in guts. I lure the walker to me and then he always just eats me. It's so bizarre. Only thing that even designates any action is that my mouse cursor turns red when I move it across walker's knees. But I don't get any arrows or Q/E to press. I tried doing it anyway and just nothing happens. I don't get it. What's going on here?
