Roofs still Missing and Columns Changed Back

I just updated my game about 24 hours ago. I did not update at all last week after your last update to the game.

Prior to updating I removed my mods and after updating I restarted my laptop and then went into the game and started a new vanilla save. Last night I built a small cottage on columns, today the roofs are missing and the columns on one room has changed back to the solid platform look.
