I've been building my bouse and all the sudden I noticed that my stairs to go upstairs are missing and when I try to put them back it glows green as if I can put them back but when I click where I want them to go, they don't go on and a sign says op generation failed.
DanaCamila7 Can you take and post a couple of pics. It's hard to tell what you have going on by what you've posted.
If you would like someone to take a look at the build, I'm willing to do that. Just upload the lot to the Gallery and reply here with the name of the lot and your username on the Gallery if different than the one you've used here (DanaCamila7).
Hope this helps.
