I am also having this problem, its driving me up the wall the amount of silly little things you find wrong that you wouldn’t even notice it is wasn’t for this one big problem with not being able to carry on with the main story which is the aim of the game is it not?… ive also had the same problem as a few others with the “obstructed” and “invulnerable” when there has been nothing around to make this little annoyance happen.
