Heatandclimatelib is not being affected by it and is not getting diminishing returns

Spice of life uses AppleCore. Integration steps are located at: https://github.com/squeek502/AppleCore/wiki/Integrating-food-items-with-AppleCore
I think to make compatible, DCFoodItem needs to use player.getFoodStats().addStats(this,stack); instead of player.getFoodStats().addStats(getFoodAmo(meta), getSaturation(meta)); as this passes the stack. Not sure how to add compatibility of food metadata

Thank you for the information! Next time I will try to refine DCFoodItem.class.

It fixed in d65f445.

They are not compatible. Moreover, there is no plan of correspondence.

Because it seems that Mod does not include API for compatibility. Probably, that Mod requires a configuration file created by the user. It seems I can not prepare.
