Oh i had save issue before creating a world! So i got a New pc, and there was a problem with gt6 ore helper: i would create world but it wasnt on a list, but removing ore helper helped.
Then there’s problem with ores being unknown.
As for the anvil: i got galena, came home and smelted it all in a furnace, then i crafted an anvil, made one lead plate for a bucket, placed a Hammer on it and then left for clay. I belive i didnt reload the game but im not shure. Ill try to recreate this
