HeavyHitur, just tested it and it is work as intended, i.e. its multiply all ore you mine, also its cannot damage save as there is no any new or altered object or something like that, only changes in difficultySettings.xml, and cannot corrupt save data, this mod only allow mine whole stack of ore from ground by hand.
Also tested on beta branch and its working fine.

this stopped working 2 days ago, it worked for a short bit. now the game wont load unless its removed. if you go back in and resubscribe it doesnt work in game and it has to be removed before restating the game or it wont load up correctly.
