After update Unity to version 2.5, I can’t rename my prefabs and objects in Project wiev.
Therefore I cannot import my project to Windows because there is an error at export Cyrillic named files. And not only Cyrillic. Many objects lost meshes after importing.
What happend? 
I remember not being able to rename objects at one point (though in 2.1), because one of my scripts couldn’t compile due to some error. Or, I believe that was the problem, it’s some while ago…
Maybe you have a script which isn’t compatible with 2.5, and therefore don’t compile? Just a thought, I’m not very technical 
My problem not with scripts. My problem with imported objects, prefabs, and even with folders. Not all, but any.
I nothing understend…
