Switch Community Center and Museum Progress Gone - Multiplayer

[souwoup]

I've been playing co op with my partner for about two weeks and our connection failed and when I tried to open the file again, it was gone. I saw on another thread that they found the file in the load menu as a default character. I was able to retrieve our co op farm, but all of our museum and community center progress is gone. I saw a couple others say the same thing with so solution yet. I was about to just attempt to restart the museum and community center, but all the plaques are gone from the community center too, so there's no way to progress in it.
I really don't want to restart cause we just got to year two, but I don't want to not be able to progress the community center either :(
