I had a few issues with rovers being buried, tweaking world stabiliser to 20.0 maximum height adjust (from 2.0) seems to have fixed it Really is working well in the short time I've been playing.
One thing I think I remember doing from an older version was re-programing without reloading the vessel, this helped a little when spawning on cliffs or undergrond and It might be useful to re-implement for situations like Zosma Procyon experienced.
I'd be happy to test fly any updates for you.
