With this update I've added a new feature in the config.yml file, the limit-lucky-blocks, this feature will make it so that only "legit" lucky blocks ( the ItemStack has to be the same ) will give rewards, for example:

If a player places a lucky block and breaks its valid
if a player places a note block and a lucky block has the note block its not valid
if a construction contains note blocks and a lucky block has the note block as material is not valid.
