This is something that has been happening fairly recently. When I'm building a room with multiple windows, I've been unable to place multiples of the same curtain on those same windows. Some of the curtains will snap into place but others will snap only to the outside of the window (which looks absurd).  Using alt place doesn't work nor does moveobjects in trying to get the curtain to snap properly. The only way I can work around this is by moving the window and placing the curtain first with the move objects cheat and then placing the window in place again. This is not the way it is supposed to work though and it didn't do it before. I can't pinpoint when it started acting weird though. 

I'm currently working on a save that isn't used any mods or custom content so I know that isn't the case.
