Just to clarify, to avoid confussions!
Just don't delete the 0.8 version, and see for yourself which saves you have in the 0.9 build.
If your end save is not there, then launch the 0.8 and save in a position that you will be able to see.
And FYI, due to saves:
My saves are OLD, like 0.4 or something like that and never had problems at all (I usually keep one save from final, play through alpha to see the content, and redo when the final is released with the defintive choices for each save, so all my saves essentially comes from a Final version, and that way works perfectly)
The PSA from PilotLara should be in the frontpage tbh.
PSA: Chapter 9 has a new save slot UI. The new UI has 3 rows and 4 columns i.s.o. the previous 4x4. This effectively means that you can't access any saves that were on row 4. You might want to move them/rename them before ch9 releases.
It's not the 4th column!, it's the 4th row that will be removed!.The 4th column in the save slots will be deleted. But I think there could be an increase in the number of pages in the save slots.
