To update my original post, the same night I posted that reply I had one crash issue during travel. After that, like you, the occasional times it did crash were more often during a save than travel, although both happened a few more times. Definitely MUCH better than before but it is a pain to have to manually save (and do so often). Once the issue was corrected, though, I blew through the rest of the game in just over a day. What I found that worked best (although still not perfect) was having 2 manual save files, and each time I would choose to save (which wasn't every load screen, but probably every 2-3 load screens), I would choose the older save file to overwrite. So constantly alternating save files. I'm a bit obsessive compulsive so this probably wasn't necessary, but that way I never lost much of my playtime, and ***IF***, god forbid, the save file corrupted completely, I wouldn't have to download the application saved data from online storage, which is only backed up once a day at best.
Good luck on the rest of your playthrough. No spoilers, but the ending is very good and A LOT of choices you make in the game (especially during the last act) have an effect on the ending narrative, so make good choices!
