After I accomplish something in KSP, I like to check up on any timed event (launch window, rendezvous, departure, etc) I have before logging out. I do this instead of fast forwarding days, and may have multiple missions going on at once. I had just completed a mission I waited quite a while for at Duna and docked everything to wait for the return trip back (160 days, bleh), so I went back through to update my events. Checked my launch windows, then decided to check on timing for my probe that was headed to Jool. The second I select and switch to it, BOOM, it goes up like a roman candle, pieces floating around everywhere. Would this be the kraken I've been hearing about? Pertinent info: I haven't flown anything beyond Duna (besides this probe) at this point. There was no debris that I had left out in space that would have run into it (I actually build my craft to avoid debris, including staging).
