@Caigan The blueberries thing has been around in various packs for a while, and usually hits all three of the duplicate berries from Natura. I think it has to do with the fact you can use either in Pam's recipes. Assuming barrels and drawers can OreDictionary them, it shouldn't cause issues beyond basic chest storage though.
The multiple berry thing is a config option in Pam's, @Caigan has it enabled.
