So when I set a hardness level on the server side server-config like 'minecraft:stone@30' in game on the client side it still looks like i'm breaking the normal hardness then when the block break it blinks back into existence, then after some time it breaks. Though sometimes this does not happen but eventually it does. This is for the 1.0 version of the mod using it for 1.14.4 minecraft.
