Also I have completed the DLC, Murder on Eridanos.
I moved the install from the Xbox SSD expansion to internal drive to see if that made any difference, no difference. Certainly seems like a SSD access issue.
(I have the Disc in the console)
Simple, any save type in Peril On Gorgon, new save, overwrite save, game crashes to dash board.
I've uninstalled and reinstalled, no success.
Playing without saving, will crash on location transition and have no progress kept.
