I've actually been noticing this for a while, but I was not certain about this until today.
The quest counters are not working as expected.
For example:
Today I have the quest to create 8 popcorn balls.
I've made 7, but the counter only shows me as having made 5.
That means two of them were not counted.
This was an easy to notice bug because I always check quests BEFORE starting a session.
