Can I get an explanation for why this bid never happened? Is it because I only added the snipe about 90 seconds before the auction was set to end? Was it not registered in the server?

I was surprised because all my other snipes have worked and I've never had a problem before. I checked the FAQ and checked the conditions - my bid of $76 was well over the minimum bid amount (as you can see on the bid history, the winning bid of 70.93 was only a dollar over the previous bid).
