I have a similar bug. Except for me it was stuff I had done that day PLUS stuff I had built over the past few days, including when I was playing the world on 1.5. Most of my house vanished, including all chests etc., my paddocks with cows and sheep (these were the only things built in 1.6), my sugar can farm and most of the outer shell of the new castle I was building. It's really annoying cos I've lost stuff I'd gathered from days in my mine.
