if the server update do i lose all my redpower2 copper etc? if thats the case what kind of id is the tin and copper from redpower so i can transform it into another kind of copper thanks (asking about tin copper silver)
If all goes well. All your redpower2 ingots and stuff should turn into NumiRP ingots. Or if something happens to that, we'll just change the ID to something else so no one loses anything. And you CAN check yourself, it's not hard.
