First of all, it is now so dark in many places that I can't tell what I'm looking at. However, there are now many invisible walls preventing progress without jumping around hunting for a hole. This is no longer possible once at the secure mine defenses objective. Neither I nor my teammates were able to access the generator for the last turret. We were able to jump onto an invisible ledge over it, and jump behind the fence to the back of it, where we had to grenade ourselves to escape. There was no way found to progress beyond this, despite four players spending minutes utilizing bullet and AOE weapons, and a concerted search for invisible doors.
