So i consider myself an above-average player i KSP, iv'e done great things, SSTO-spaceplanes, 350+ tons payload to orbit (2354 ton at launchpad) and so on...(all stock, no mods ) I've spent sooo many hours planning my mission to Jool and all the moons, manned landings, planting flags and so on, including a return to Kerbin. So i get on my way, get a nice intercept with aerobreaking....only to discover...with no quicksave to rollback...that i am...going the wrong way around Jool...facepalm...
