Hi sL1u.k,
Thank you for the bug report and for the feedback. I went ahead and fixed the bug you found and also lowered the requirements from 5 to 3 for bits, from 10 to 6 for stones and 3 to 2 for hearts. I also added a 20% chance during wander option to find a black market seller who will let you choose whatever item you want to buy at an inflated price. If you happen to find an egg, you can also level the bond with your pet and eventually farm materials daily from it. Hope all that helps! Happy hunting!
