Even with version 1.3 the issue remains. I still can't climb terrain. It just doesn't finish the climb and ends up making me fall back down.
Even when set to Low, which even if you have it set to Low at launch it for some reason kicks you back to High, the climbing system doesn't work. It times out with almost all of the climbable objects. Turning the tunnel into a great big wall you can't get through because the climbing system keeps kicking you back down.
