What is happening:
the names and faces for High Harvest and Windy Seeds become messed up a bit during the dialogue (WindyS and HiHa).
strangely, it fixes itself later on in the dialogue.
Steps to reproduce the issue:
start the quest, talk to High Harvest. if i remember correctly, it happened 3 or 4 clicks into the conversation, then fixed itself a couple clicks before the 2nd screenshot below.
