Ok I cannot reproduce it for now because it keeps landing on the "green terrain".
Now I remember that last years, it crashed 100% when it was landed in the desert. And this time, it was on the snowy terrain. So I'm wondering if its related to this type of ship to this type of terrain (I have no idea how the script works)
It will probably happen again and I'll keep that in mind if the conditions are mets (I'll make sure to save just before)
I'll keep you posted.
Thanks!
