Rocket Explodes at "log in"

[Zosma Procyon]

I've had an occasional probably of some of my rockets exploding when I try to "log in" to them. These are already underway, and there is nothing around them for them to hit. Is this a known bug?

A little more info is needed.  

KSP version?

Most recent verison, Mechjeb is my only mod, and I'll look for the log file.

Actually I just reloaded KSP to undo this random explosion from my backup drive, so I cannot provide the log.

While I don't think is relevant, make sure you are running the latest mechjeb

As far as I know, although my current is over 2 weeks old.

Also make sure to hit F3 the next time it happens. Maybe there's a "resonable" explanation like overheating that can help with tracking down the problem.

In my experience this usually comes from clipping parts in the VAB.  Sometimes they'll load OK on the launchpad while under gravity and supported by launch clamps.  Then after reaching space, saving, exiting, and reloading the craft fresh, it decides there are internal collisions and explodes.  Usually the F3 report will say what collided.

I can't think of an easy way to save the ship in flight though, without extensive persistent file surgery.  Warm up the rescue boat

I think I've seen this, and it appeared to load the engine turned off (on while saved).  The physics started, the engine lit, and the additional forces blew up the rocket.  I wrote it off as a Unity engine change bug.
