Coconut Scream Pie (and future anniversary offerings) should generate an extra chest

The past anniversary offering had the unique quality of creating one extra chest in the map. While Survivors already had that ability with offerings to generate more chests, killer didn't have offerings like that before. However, there was no advantage to more chests being in the map for killers. So most people, me included, used it purely as a BP offering.

That was until the perk "Human Greed" was added. This perk shows the auras of Survivors when they get near chests. So more chests means more aura reading. Suddenly, there was a reason to preserve the past anniversary offering. As you could get an advantage from it. Ghoul, Springtrap, Houndmaster, Dracula and all future killers will not be able to use Human Greed to it's full potential.

Now the new anniversary offering doesn't give extra chests. This means that the old anniversary offering is a limited resource that can be used for an advantage. A bit of an extreme example but imagine if they suddenly stopped putting Styptic Agents in the Blood web. Sure, you don't need a Styptic plenty of games. But that wouldn't change the fact that it's a limited resource that gives you an advantage at times and once you run out you cannot use them anymore.

To solve this issue, either give Coconut Scream Pie and all future anniversary offerings the ability to create 1 extra chest, or give killer a generic +1 chest offering. You can retire the common (brown) rarity BP offerings for it, to make sure the blood wen isn't too clogged up.
