I kinda got accustomed to 'press and hold jump button' not working after loading the game. Jump once, works fine, you're good after that - if enemy didn't hear you.
Now I just finished mission for the poor cop in the lab. Walk in, scan some stuff, former coworker barges in with no notice... boring and not why i was sneaking, but not the point, Walk out and jump button does nothing, Played for half an hour, got shot, ran into the street and got hit by a car, no change.
I will give you that it might change after fast travel or driving, but what if I don't intend any of these?

Could be good game after another 20 patches. Right now, from creators of Witcher series? Disappointing.
