For me dying didn't worked the classical way - being killed by enemy or jumping off from mountain/hill (jumping off especially since you are saved by hydraulic suspension in your gear that helps you survive high altitude jumps, and knowing that mountains aren't straight pillars, meaning that you wont fall the whole height of the mountain, you will land on a nearby side of the mountain since you have not enough distance from it to make that vital landing, so you will not die from a jump).
What worked for me was when I was in the sinkhole, I had this bug that loading autosave I got into sinkhole in order to get that mining drone in it because of developer lack of attention, so after I got out by teleporting to some forward station, I couldn't get back on Tempest no matter what, so I read here solutions and I tried all the ways I could die which didn't helped until I tried to reset myself by driving in a sinkhole again, which reset the bug because out of mission zone thing, so probably it can either be reseted by going in places that will throw you back on the map with the automatic reset from out of mission zone places.
