It looked like to me: "We made a change (without telling anyone), and didn't think about people moving houses needing more than a few hours to relocate their stuff... oops, we'll fix that.""It's still broken at the moment but we are working on it". Thats what its looks like to me.
This is something that could have been easily avoided. "Due to a serious problem we had to change decay rates on houses, so please don't condemn any houses without taking your items out first. This could also effect boats, aquariums, battle chickens, and other timer related systems, so if possible dry dock your boats, and keep an eye on your add-ons."
If they do this... no one loses a house or a boat. I really don't get it. :/
