does not work with water erosion mod fabric and the error code is java.lang.UnsupportedOperationException: 'Block{minecraft:cobblestone}' property 'weathering' is not available on 'Block{minecraft:mossy_cobblestone}'java.lang.UnsupportedOperationException: 'Block{minecraft:cobblestone}' property 'weathering' is not available on 'Block{minecraft:mossy_cobblestone}'

I also am on 1.20.1 so i would prefer the fix on that version if you only can do it on one version for now
