All placeables that sat on wedge foundations disappeared

question

Smelters, chests, cupboards, you name it. If it sat on a wedge foundation when the 500 patch came in, it’s gone. What could the possible cause for this have been? And should we be worried for the future? Can it happen again?
Also, is there any chance that we could get our stuff back? Many people lost entire fortunes because of this. Maybe with a script that restores everything that was deleted one second after the patch went live or something?
