More Avaritia uses multiple recipes that require diamond singularity and emerald singularity, while Avaritia-Kedition has removed them. When loading the game, More Avaritia cannot find the diamond and emerald singularity, causing it to crash. Perhaps you can add some configurations that, when enabled, will regenerate diamond and emerald singularity.
