What happened to my scene? Editing it and *pooof!* gone!!

My very first real scene. It was going great and I'd just gotten my lighting just right. Suddenly (and boy do I mean that!) almost everything I'd done in the last 2 hours was gone! I know - I should have saved it sooner, but I was excited to see everything working. The only thing that makes sense is that I was playing around before I got serious and deleted a game object from the scene. I see in the log where it seems to be saying that a script is missing. Could that mean that the object was missing? If so it's badly worded. Deleting a gameobject shouldn't crash the editor! And the console was hiding behind my browser on another screen! Have to say I'm very disappointed now.

Before I go back and start over (Gah!) I want to ASK two things: is this normal behavior and I can expect it to happen again at any moment? And 2nd is there any possible way to recover what I've lost? Below is a bit of the log:
