Makes it so that the server checks if players have mined ores (this also counts for deepslate and nether ores like Quartz, Gold and Ancient Debris!). Players can use the command /listores to get a list of all the ores they have mined in chat so that they can see how much they have mined in total!
The server saves players progression the moment that you close the server, so you won't have be scared that you'll lose the progression of your players!
