I lost my town too(my fault though). Everything gone. I had years of work. Like you I had all the museum sections full except the art, full house upgrades and all the furniture sets I wanted. All golden tools all main street shops and upgrades. I was working on setting up stuff in the display rooms at the museum.
I didn't play again for months I was so upset. I have since started a new town and am working on house and main street upgrades, pwps and perfect town status as well as filling my museum. The thing that bums me out the most is the dlc. It's going to be much harder to collect this time around. And losing certain villagers that I really liked(Bob, Cherry, Lolly, and Ceasar). It's hard to lose all that work that you put into your town.
