"For Corbin Day, you can email your save (or a Dropbox or Google drive link, etc) after completing that quest, and before leaving Reaper's Coast, to supportdos2@larian.com. I can teleport him to the ship in the developer version of the game, which should get everything to work properly after moving to the next act."
I can confirm that this works, thanks, Raze.
