In case it helps any later readers of this thread: I did get my flights back, by restoring from backup. I replaced this folder (remember this is on the Mac, using Steam): [Computer User] > Library > Application Support > Steam > SteamApps > common > Kerbal Space Program > saves > [user/account name]. Note that this reverts not only flights in progress, but also ships and subassemblies in the VAB. Thanks again!

Thanks, John FX and Otis. I'll dig through my CrashPlan and see if I can recover more recent Quicksaves. If not, I'll have the fun of tweaking my vessels and re-launching them better than ever. I'm a new user, so I only lost about 12 flights. Thanks to you both for easing my learning curve with tips on additional/alternative mods and quitting out with ALT-F4! Brooke

This was the series of actions: Had trouble in VAB with items not "snapping." Thought, "Well, try it without mods." MechJeb is my only mod. Quit KSP and removed MechJeb from the GameData folder. Relaunched KSP, and received series of notices saying more or less "[vessel x] not loaded because component missing." Quit KSP, put MechJeb back into GameData folder. Relaunched KSP. All vessels that had used MechJeb have vanished, apparently permanently. Any hope for me? KSP 1.x, Mac, through Steam. Thanks! [Addition: Looking in my user folder, it looks like my only existing Quicksaves date from before January 4th. I'm not sure, but that could certainly be when I first installed MechJeb.]

Reactordrone, it looks like that was it! I toggled f4, and it's on. (At first it only showed distance unless I moused over the object for the name. Later, it showed distance and object.) I must have pressed f4 rather than f5 sometime or other while quick-saving. Thanks! I'll look again at key-bindings to see what else I might be missing. Brooke

Hello! Following tutorials and YouTube videos, I have succeeded in managing a number of rendezvous in orbit. (Yay!) I have watched my targeted item come into view and go out of view, and have approached withing a few meters. However, in all of these tutorials and videos that I see, the targeted object (in Staging) shows a yellow readout of its name and its distance. For example, see here at the time-tick 04:54 in this Scott Manley tutorial: https://www.youtube.com/watch?v=srsiLZLPiv0#t=4m54s But the objects that I target, and with which I rendezvous, do not show this yellow display! To check my distance while approaching, I keep having to switch to Orbit Map and mouse over the targeted object. I have indeed set the object as a target ("Set Target"). Any ideas? I am using version 1.x on Mac (Yosemite). Let me know if I can add any information. Thanks very much! Brooke
