Yeah, I was thinking about some work-arounds. Perhaps not entering the runway/approach until you know what it will be for sure. And just don't use vnav for descent and manage it yourself. It's kind of a drag because that's what the FMC is for, but until they fix it, this might work.

Also, I've been wondering why some people don't get this crash. The people who are crashing are you using lbs or kg? I'm curious if that could be a cause. I've tried both PW and RR variants and it makes no difference.

I could be chasing my tail here, but until CS fixes it, I'm very frustrated. They won't return it, because I had good faith and have waited for a fix, so it's been too long now. I'm stuck with a very broken airplane.
