Did you unlock them yet? You need to at least meet Willow.
I've met willow and all of the characters say that theres no more content in this update despite still have blank spaces
Can confirm...something glitched out. I started a new (speed)run and skipped just about everything. Just met willow and immediately went to the meadows and found them
You can try using the console to fix it. Copy & paste these two:
fair.locked = 0
fair.locations = {"morning": meadow, "noon": meadow, "afternoon": meadow, "evening": "unavailable", "night": "unavailable", "midnight": "unavailable"}
