If you look at the current list of cheapest Melody items, you'll see that there are very few cheapish items there and also that their prices are rising gradually. So yeah, the pool for that slot is super tiny atm!
I guess RB really does need a check-up. It's a bit annoying. x) Here's hoping Keith returns to the recent RB update and sorts things out eventually.
