Ore Regeneration
As the name implies, this plugin aims to automatically regenerate ores! Don't worry, it works even if the server stops. (It simply regenerates all ores on server startup that were broken).
Config
It is really simple to configure what ores to regenerate! Simply go to the OreRegen folder in plugins, and open config.yml. Inside, just add to the list ores that you want! (There are example ores in there from newer version just for fun, this mod is only aimed at 1.12.)
To check the name of an ore, just keep open your server console, break a block, and it should output the name of the ore as broken to the console. For example a block called Ruby from a mod called Ruby Paradise (Fictional names, any similarities is purely coincidental), then it might be RP_RUBY.
Future Things to Add
