A player used these two mods together and the game crashed.

java.lang.IllegalAccessError: Update to non-static final field net.minecraft.class_1792.field_18672 attempted from a different method (setFoodComponent) than the initializer method <init> .

AllStackable adds a new field to Item.class and injected a piece of code into Item<init> to initialize it.

    @Override
    public void setVanillaMaxCount(int vanillaMaxCount) {
        this.vanillaMaxCount = vanillaMaxCount;
    }

    @Inject(method = "<init>", at = @At("RETURN"))
    private void setVanillaMaxCount(Item.Settings settings, CallbackInfo ci) {
        setVanillaMaxCount(this.maxCount);
    }

LatoOrigins modifies foodComponent using an accessor during the item registering, which is after the first value assignment.

I don't know why these would ever conflict.

KrisCris/AllStackable#14

I am currently working on a fix for this by changing the way the origins eat.

This has been fixed with 6bcd5a4
