I'll investigate this and return to you. Hopefully there is just a trigger somewhere that was not immediately clear. I'll try looking for it.
EDIT: What does it say for Featana's Character log? I'm trying to see if a flag is missing. If you cannot visit her at the farm, then maybe something is wrong ._.
Also, if you have discord, and you can send me your save file, I'd like to look into it there too.
