So the issue is that the carpenter isn't at his house. I've built it and talked to him before but now he's not there. I've slept a couple of days and waited but he's not there. Jade is still there though. Help?

Thanks for your report!
It sounds like you are using 0.5.x, most likely playing Farming Valley I assume?
This should be fixed in 0.6.x :)

um this is just harvest festival

oh and some other mods
