For Dying Light being a 7 year old game there's still a lot of bugs with doors. I know you can climb on and through stuff to get some places, but the mission waypoint is marking doors to walk through. For some reason it either wont even let me open the door or wont update when I do. It doesn't happen all the time and sometimes quitting and loading back in helps, but I shouldn't have too. Still love the game though.
