Bug state: both crafts partially buried, rover wheels two-thirds buried. Wheels spin freely, though yield no motion.
Possible bug reproduce actions:
Enter, slowly fall, an successfully land on Sergeaas successsfully. Successfully move around an over terrain.
Quick save first, or: drive within 5 m/s briefly, slow down an stop, then quick save. Forgot which order.
Then quick load, or load in from a save-an-exit save. Loading from either a quick-save or a save-an-exit save loads the crafts as partially buried an immobile.
I list this report as v1.2, as this is my second encounter out of 2 distinct successful land encounters on Sergeaas, so far.
Distinct, as in: this one was taken from fresh new sandbox save. My first encounter with this bug, to be stated in another similar bug report, happened in a career-mode save. Crafts for both scenarios were nearly identical, besides a few extra parachutes and repositioning head lights a bit.
This is while playing from iOS.
