Whoa man, did you murder a baby or something? Karma is out to get you.
Sorry to hear about all of that, your poor car! AND WALLET!
I'm always nervous when jacking mine up, but fortunately have never had any issues like this. I always use ramps when I can, but obviously, this time, you couldn't, since you were swapping wheels.
On a side note - I'd keep those Winter tires on a little longer, we're not quite done yet, despite the warmer than usual Winter.
