EVA at KSC wrecked save game (kerbin GONE)

[tater]

Had a parts test contract landed, and figured I'd give Bob a job to EVA and walk around a little (needed a couple points for the tech tree for my mun mission).

Did tests, EVAed, and screen went black. Reverted to VAB, tried again… in space, but nothing else shows. Quit, reloaded save… no Kerbin at all, gone. So much for my 1.0 career.

Don't forget to quicksave tater.

LOL, I don't normally QS ever. Guess I will now.

^^^about a zillion of that last line, with the odd set of:

thrown in here and there.

I should add that I have never had something like this happen before in earlier versions. I've had some isolated weirdness, but nothing catastrophic.

Occlusion test is new for 1.0 so no one would have seen it prior to this, very strange, what about other vessels in that save?
