In the main quest that allowed me to transition from level 21 to 22, the musk fragrance bonus item I should have received did not appear in my star menu. At completion it did show the animation of the bonus items going to the star menu, but it did not appear there even after over 30 mins waiting.

I do not know the exact name of the quest, as I discovered the missing item somewhat after, when the quest had already been automatically removed from the list. I also cannot reproduce it as it was one of the main quests to level up, which I can't repeat.
