I've completed all puzzles. Puzzle 16 is giving me issues because it won't update the status. I've talked to the ghosts and all that but it still says that puzzle 16 is not completed? What am I missing? I followed the steps in the strategy guide. Also when I put my villager to talk to the ghosts she was transported to the research room after the ghosts told the story. I don't know if it's a technical issue or not. I'm just very sad that I finally completed the game about 95% on my own and of course NOW I have problems at the end.

Others seem to be having problems with this too...check this thread and see if it helps.

Good Luck!
