Found the following Last Exception file before relaunching the game. Seems to have 2 desyncs 11 minutes apart, one has something to do with carrying something, the other has something to do with a playmat. I aged up a newborn just before taking a vacation in Granite Falls, and placed a playmat and a crib in one of the lodges using freebuild mode.
