The feature that auto-picks up money and ammo is neat, but seems very inconsistent; sometimes I auto-pick up money and ammo that I need, sometimes I have to manually pick items up. I'm talking about the feature that collects without a button press, not the long-press action that picks up all "minor loot" in the area.
What's the trick? Are enemy-drops auto-collected and container loot not picked up? I think I've been observing that but I'm not sure.
