I've had problems with new missions implemented in the game, such as when charging once they've been done and charged, I mean the ones that say
1) Celebrating the new quest Boox part 2 (Grace Vela): this mission asks to make 72 or better in WRT the box of the costume baroque is empty (once I opened it) and I disappeared the prize
2) Celebrating the new quest Boox part 2 (Grace Vela): this mission asks to defeat Anthony in Gleiger, also the same does not appear reward for the mission performed
3) Celebrating the new quest Boox part 2 (Grace Vela): This mission asks to make 50 berdies in Special Happy Course, once also fulfilled when charging the mission the box is empty and the prize disappears.

I had the same issue with the Baroque costume not appearing in inventory. Finished WRT mission, got next mission ticket, and no costume.

Yes seems to be the consistant error for the barogues box, mine came up empty as well. I finished the 50 burds for the special course, got the aa S 7 day box ... but have not opened it ... seemed like a useless thing to do with all the feedbacks saying empty.
