When Jason visits Granpa's grave, it is vastly different from when we saw it at the beginning of the season. The first time we saw the grave, it was in the open with no trees overhead or surrounding it. It was surrounded by large boulders. When Jason walks up to the grave, the boulders are gone, and the grave is surrounded by trees, with a large tree providing shade over the grave.
Act Three ends in the early evening when Jason leaves the house to spend the night on Grandpa's Mountain. Act Four begins the next morning and then vacillates between scenes from the night before and current morning.
At start, scene has Army vehicle with white star on rear door. It should be on the front door.
