Build mode on Basement Levels, Glitch when moving a room to new location

Hi, I am trying to report this glitch to let people know there's an issue. I don't know where else to report this. I'm not on Twitter. It started with either the first update this past week or the first emergency patch. 

The glitch happens when you try to grab a room and move it elsewhere. After you move it, what's left behind in the original spot is an uneditable duplicate. You can't delete it, move it, or grab it.

This happens when building on any of the basement levels, not on the ground or above-ground floors. I'm not trying to duplicate the room; I only want to move it to a completely different location.

The issue is only when moving an entire room (empty or furnished). It doesn't happen when trying to grab a wall and place it elsewhere.

The problem doesn't happen all of the time, but when it does, it happens with every room you want to grab to move. This glitch happens maybe 30-50 percent of the time. 

I have built on basement levels a lot and have never had this issue until now.

Workarounds After Undoing the original attempt to move the room:

• Don't move any rooms but slide the walls to where you want them. Not always easy if your build is already elaborate;

• Ignore that room for a while and create the same room in a new location;

• You can delete the unmoved room and build a new one in the new place. Not fun if the room is round or furnished;

• Work on something else for a while that doesn't require moving rooms. After some time, go back and try again. It should work properly.

Thanks, you guys.
