While in editor, my craft will have entirely normal stages with engines and decouplers and such. When launching the craft, all stages disappear from the staging indicator. When you stage, all stages stage at once, causing explosions and associated problems.

When spawning craft onto the Runway, an Easy Vessel Switch message pops up with something about "easing" and I change to a random craft that's landed on Kerbin. I can't change back. Also, the craft is stuck floating on the Runway.

When time warping on Kerbin there is an obscene amount of stuttering and lag. Like, the game will freeze for 30 seconds straight, then run at 5 fps for 45 seconds, then freeze again. 

When spawning in craft, if you change windows while the game is loading, it breaks the craft, meaning you lose SAS, zooming in changes FOV instead of zooming, Z and X to throttle all the way up/down stop working, and stages don't work properly.

Sometimes the zoom stops working entirely while inside the editor, needing a full game restart for it to function again.

the more mods you install, the more it becomes likely that stuff like that happens. and i never, ever got any solution to any of them.
my advice is, as long as they are not critical, just deal with them.  in the specific case, recreate manually the staging sequence on the launchpad before launching. launch planes from the launchpad - maneuver out of the launchpad proper, then use the grass as a runway. avoid time warping while on kerbin's surface, go to the tracking station if need warping.

the thing with the zoom and Z-X being broken looks like a bug i have occasionaly, in that case just reloading the game does the trick. and if restarting the game fixes the thing with the editor, keep doing it.

sorry, i know it's not the answer you'd like. but there isn't anybody who can actually fix your bugs, so if you want to play with all your mods you have to play around the bugs. sometimes it's worth the effort, i've done it. In my kerbalism+rss mission, i recorded no less than 47 bugs. 90% of times, the solution was one among "reload the game", "restart the game", "ignore it and include a greater cost into mission planning", "don't do that thing".

otherwise, you have to play stock.

I'm unable to interact with my stages whatsoever. My staging indicators are completely and utterly empty, and when I attempt to stage, every stage on the rocket fires at once. Not because there is only one stage full of all the parts. Stage 0 has no parts inside it. I can't fly anything whatsoever and I need to figure out this problem above all else.

I mean, it's such a strange set of bugs, I've never seen anything like this before. I wonder if BDAr-

Oh no.

UPDATE FROM FIVE MINUTES LATER

So after validating my files none of my issues went away but something extremely weird happened. Early game I sent Jeb, Val, Bill and Bob on their separate doomed landers to the Mun and Minmus. They're all still up there, with Bob sadly being killed in an EVA accident. But I look at my available Kerbonauts and... Jeb and Bill have randomly appeared back in the Editor?? And the craft they were on have disappeared from Minmus?!?

Please help. My save of over 100 hours is slowly corrupting and it's nearly making me cry. I've poured all my passion and motivation for this game into this singular save and now I can't even take off in a rocket.
