For some reason everyone in the game that I should be able to 'talk to' in order to receive a quest has vanished from the map. there is just a blank space where there name should be. i cannot receive hours of prosperity, any professional quests, or any other new quest which arises. i've tried refreshing, tried giving it a few days and it hasn't seemed to sort itself out. I've spoken to a few other people in the game and they don't seem to have the same problem. if you could let me know how i can fix this it would be great.

Thanks
