Try to make a little more efforts for your customers.
It's easy to fix the issue, just ask for previous choices before an episode (like Bioware made for Mass Effect for exemple).
That's what I suggested to the support before, in case our lost saves are not available any more. I'm not sure if you can ask for every little possible decision you made before to recreate with a set of questions. But you could at least insert an option right before you start Episode 4 what major decisions you made in EP 1-3 (like "Help kill Larry", "Stole Food from Car",....)
I really enjoyed your game so far until now. Bought the Season Pass straight after playing the demo to support you guys. Great Storytelling, that is the heart core of this franchise, but I refuse to spend hours again with decisions I already made, again and again just to see minor differences for the story.
I heard that every patch does generate license costs the publisher has to pay to Sony, but you would dissapoint a lot fans and customers if you didn't offer this service.
