Hello all!
I just made an account to bump this up: I am having this problem too. Had the Pillars series in my account for a few years, but only recently started playing this through last month to prep for Avowed.
From what I had searched up, it looks like the latest version of PoE1 is causing issues importing saves... I started my playthrough I would like to import on the latest patch, and so I cannot import anything into Deadfire.
I don't want to play through the entirety of PoE1 again on a legacy patch just to import a savefile, so I wanted to reach out and ask if there is any other solution to the problem. I don't want to play the game unless I am able to make sure all of my different choices were taken into account.
