Hey, that same girl froze my game as well. It was odd, though, and I can't know why. I had just caught a Budew in the grass below her, then I spoke to her and the game froze here (I was using Beta 2.4):
I say it was odd because later I went to heal my team and then saved and tried speaking to her again, and it went well.
Also, two more silly things:
The music here stops after a while, don't know if it's intended or not.
This is simply a typo, it's not important, it should be news.
Really enjoying the game for now, I really like how many paths there are to visit later, the game is very enjoyable!
