The further I get into this game the more issues I have with it. The other night I went to pick a flower and the camera started to pan around, but I never bent down. Marston just stood there and the game wouldn't let me do anything another than look around.
Then last night I went to loot a couple of bodies and it wouldn't allow me to so I figured it was part of the mission, but when I reached the guy I was supposed to be helping I wasn't able to interact with him at all. After a couple of minutes of trying to figure out what I was doing wrong I realized that I couldn't shoot, switch weapons or anything at all. When I tried to shoot (with the repeater) it would bring up my fist and even then I couldn't fight. It kept randomly switching my weapons.
Tried playing a bit later and when to throw some fire bottles, aimed, but wouldn't throw. Then came the weapon/fist issue again.
