Hmm, can you send over your save file so I can take a look? it'll be in www/save, and the slot is the file name +1 (example: Slot 5 is File6.rpg)
Thanks for that! I went and fixed it up for you, please download it here: https://drive.google.com/file/d/1TylAhbYNes4DiSrt5iUZpAxVgNavP_f7/view?usp=shari...
Let me know when you have it downloaded and I'll remove the link
I think it's caused by a bug with you running out of time on the day where you have the conditions met to see the merchant. I'll have that fixed in the next patch
