Okay so I recently lost my palladium drill and I had to make a gold pickaxe so I could mine, unfortunately the pickaxe does not work on any ore (I can't tell if the ore I tried mining with it was palladium or copper, it won't even mine crimson rock). I can mine dirt and rock just not ore. What is wrong here? Please help. To add on, I also tried mining with a lead pickaxe and still no luck.
If you are not able to mine any ore at all, your save file may be corrupt, and I suggest you create a new world, and try to do the same thing. If the same phenomenon reoccurs, you should try to re-install the game completely, as this is something that should not happen under normal circumstances.
