It is so easy to misjudge statistical events. If the stuff in those 25% of boxes with loot is similar in amount to what people on 100% would find then it is exactly as you want it. Only if the loot in there is reduced as well would there be a bug.I think is been an issue all along. Way too much empty everything, empty airdrops, empty food piles, empty med supplies, ect. I made two previous comments directed at Gazz cause hes the man who handles the loot tables. Also things like college jackets, running shoes, and mega crushes are supposed to be the keys to nightmare speed, I've found 1 mega crush in 32 hours playing and the others don't seem to exist, tires don't exist, and neither do bottles of acid. Pretty much become 100% dependent on the trader and it shouldn't be like that, if you look at the description of the loot abundance option it should just be less in each container, the way it is now it is like only 25% of the containers have anything in them and 75% are empty on 25% loot. I can get by as well but at the same time it is inadequate.
So make a test: For example make a new game, loot 60 kitchen cup boards or trash piles or any other frequent loot box. Restart with 25% loot and do the same. Compare the stuff you found by multiplying the stuff in the second run by 4.
