add DLC save

[proper lark]

I currently cannot complete any of the DLC’s as they don’t have a save feature, the game seems to either crash or drop frames severely before I manage to finish it, this causes me to lose my progress everytime

This was added in Patch 4 already. There's no point making a suggestion on this because they're updating consoles

this is already on consoles (execpt switch)
