It seems like you made mini-suggestions for both the Festiviser and the Fuka, but then used their outdated prices anyway. You need to use the values established by the minis, but the hats used in your mini-suggestions should also be in date. The Naggenvatcher isn't too far off since that price is only 4 months old, but the Mining Light's price is old enough that it was most recently priced in buds. That's too old to be considered reliable.
