I somehow can't repair my pickaxe, it says it's too expensive, I tried to remove it's name "Starter Pickaxe", yet nothing changed, I usually use diamonds to repair them and it doesn't work now, I tried making a new pikcaxe and repair it with my Starter Pickaxe but it still says too expensive.
You can get it fixed by asking a donator to use /fix on the pickaxe for you. However, some persons may scam your pickaxe when you give it to them to fix it. Do this as your own risk.
You can only fix it in an anvil a couple times, you can't just do it over and over again, the more you fix it in an anvil, it will be more expensive to fix it and on the end you will not be able to repair it anymore. You can always trade with someone to fix your pick (be careful cause you might get scammed) or get a rank so you can /fix it by yourself, although xph11 said there will be a fix sign soon so you will be able to fix it just by paying some in game money.
