Still running the early-release version, there is a tiny bug I can report : I was able to buy the crown at night when the shopkeeper was not there. It was the first time I visited the place, hitting a bit randomly the action button, so it was creepy to get a sale dialog with an empty counter. During daytime, when I came back, I could see there is normally a saleslady at this place.
This didn't cause any harm, from what I can see.
The game was well worth the wait, and you can be proud of this new achievement.
