I've never actually played career mode but I have a feeling this update has forgeted up entire save files with mods so now would be a good time to start
From what I read on the KSP forums it shouldn't cause much of an issue with sandbox saves, since nothing has really changed there, bar the few added parts.
But modded career saves might not work right. At least, that's what I got.
And I'm updating now and will be playing tomorrow.
See if these starter contracts help me get into the swing some more.
I'm doing better now and have gotten a number of ships into orbit (although not all of them with a means of escaping said orbit), and I've sent a couple of ships close to the Mun.
But I've not yet managed to get in to orbit the Mun (lack of fuel in most cases), and I'll go back to the tutorials for how to do that better.
Also need to work out how to get two ships to meet up. Been trying to sync up the orbits of different ships with maneuvres, but it's not working out too well.
And I've got a few ships in orbit with no fuel, a bunch of science points on them, and no comms device, because I was really smart when I decided to send them up there.
