This is part UI/UX confusion, part problem, part QoL improvement.
I took a Townie Errand from bulletin board to give Ling 3 Peas. I grew three and on the very last day, went to deliver them.
Because you can only gift one time per day, and the peas I got from harvesting that day were of different qualities, I was functionally unable to gift Ling all three peas.
- I didn't realize all three had to be stacked and therefore of the same quality.
- That should be unnecessary. If the game offered a menu to fill three slots for a three-item errand, and you can only fill them with the requested item type regardless of their quality, that would solve this problem.
