If you don't cycle and have been away make sure you always go back to last played date to try to avoid this. But I know it is awful when it happens he must have been going to ping but didn't get there if your power cut and you didn't tt back..so sorry though.
Oh my gosh. I'm so sorry to hear that... I'd be devastated if I found my Wolfgang in boxes.
Good luck! He was the first villager to give me their picture too, and I don't think I could live without good ol' Wolfgang either. It must be a pain to cycle. >o<
