Argh… GameObject keeps rotating when I hit the play button

I had this problem a couple of weeks ago where an object in my scene would suddenly rotate 90º when I would hit play (it has no scripts attached to it and it’s just a static part of the scene).

I re-imported all models into the scene after a lot of work, and things were going fine… but then it’s randomly started happening again. It seems like a bug in Unity, but how can I get around it?

Do you have animations on these objects? If not, try telling the fbx importer not to import animations at all (because, by default it will even if there are none to import)
