Hi, I can see why they got banned in the first place, someone abusing the protection bypass as usually. But since I prefer the rftools builder (quarry) due to its customization I'd suggest to un-ban shape cards/builders in farm worlds if that's possible. Thank you for considering it. Riafind
Unfortunately this is isn't possible. As per world bans work by blocking the item place. In this case the cards are being removed from inventory to avoid the use of them. Meaning once you would enter the main world these cards would be removed. While we could add the exception to the farmworld, I don't like the issues this would cause. There are many alternative quarries you can use.
