I talked to him once when I firs came to the town and was exploring, since the bug though I haven't been able to talk to any character as I run into the same problem. I think the last person I had talked to before running into this was the girl who sells seeds in town, I can't grab her name at the moment. Good Luck though, I hoped this helped!!
Hey thanks for the additional info it helps a ton. I’ll be looking into this as quickly as I can. Not sure exactly where the issue is coming from. I’m sorry to say that this might be a save wipe for you. I’d wait till the patch tomorrow though. Since I don’t know the nature of the bug I can’t be certain but the patch might at least fix the issue for you even if I haven’t found a solution yet.
