*With some AddOns there can occure a little error with the curtains. It´s possible that objects right behind the curtain will disappear. During my tests it always helped, when I took the objects (also windows) away and put them back on their place, immedeately. This error doesn´t appear in the base game, and I think the reason of it is the transperancy of the curtain. I don´t have another solution, but I´m always grateful for tips :)
