I've hit a brick wall during the "You will not rest" (the quest where you collect the pages for the ghost in the tower). I got the 1st page from the waterfall and now need to shoot at a sculpture on a chapel in the cementary in the city but no matter hwat I do, Marvin will not target the stupid thing. I've been trying from just about every angle and I am about ready to give up. Does anyone have any solution to this?
