What are the worst mistakes you've made in KSP?

It was some time in 2016. I was landing on the Mun for the first time. I had a glass of water right by my arm. I got excited and raised my arm which accidentally pushed into the glass, tipping it and making all the water spill into my computer 

Somehow the computer wasn't *too* damaged but the motherboard ended up corroding so I had to buy a new one.

Quick question: was it the MacBook or the Acer?

Not really THAT big kind of mistake, but i krakened my save into oblivion with time-warp and made my Duna Station dissappear. And i built that thing around Duna, not preparing it around Kerbin.

I accidentally rendezvoused out to a random piece of debris instead of the space station i was trying to dock to. This is the stupidest thing I've done that i can remember, but I've probably done way worse and I just try to forget it.

My biggest mistake was to start the game.
