When i broke a lapis_ore gives me a protection.

When i break a lapis_ore, it drops a preciousstone that is a lapis_ore, how i can disable this?

Hey. Its probably the AirOfAtlantis stone, you can remove it or you can set meta-autoset to false.

If meta-autoset is set to true, all block materials which are the same as precious stones ones when broken or placed will be considered as precious stones blocks. That is why when you break the lapiz_ore it generates one PS. Just set meta-autoset to false and this issue will be fixed (you have to do this with all your precious stones you dont want this feature)

Wish I was clear!
