I think Unity just corrupted my prefabs

So I open up Unity and press play, I’m hit with a bunch of “MissingReferenceException: The variable ‘blablabla’ of ‘blablabla’ doesn’t exist anymore.”

I go to reassign my prefab and it turns out my prefab has no components attached (including no Transform). The name of the GameObject and it’s children are still all there correctly, but no Components are displayed at all.

However, when I look at the prefab file in Explorer, the file is listed as being ‘74 KB’, which makes me think the data might still be there…

Is there any way to recover this prefab?

Version Control? Dropbox?
