A bit belated on a reply. How often do you experience these crashes in Orb Vallis while fighting Profit Taker? Does it require multiple attempts?
Extremely often. My main fear and deterrent when doing Profit Taker is it crashing. When I do complete one I feel lucky. So yes, it does require multiple attempts.
Do you crash during regular bounties? If so, can you please name them?
Yes, but even in Free Roam these crashes occur. As far as I can tell the crashes are not tied to a specific bounty.
Do you find yourself frequently traveling between Fortuna and Orb Vallis before the game
