Yes, there has been a change. A variable has been added that causes the loot abundance setting to be ignored for certain loot containers.
However, the system has inherent limitations. The starting point, for example, matters a lot for progress.
If the first trader is near a big city, then you have a much faster progress than if the trader is next to a small city.
I watch the videos of a youtube content creator who must have rolled a very bad map. So far 3 traders, two near small cities and the last one is in the middle of the desert and the only POI nearby is a campsite.
