Was wondering where the recollection is only to notice it's a part of your saves. It basically just saves the game right before the H-event starts and you load from there, lol.
(The reco# are you recollection saves. Game automatically saves for you before the event starts.)
This does mean that it also saves the state of Serena's pregnancy when the event took place without you being able to control it. Only way to change it to your liking is to delete the recollection save and re-experience the event with a different pregnancy state.
I.E if the event was saved with a bloated belly and you want it not that, you have to delete the recollection save and redo the event to whatever you want.
Important to note that certain repeatable events like a lot of prostitution events will not be saved here. You would have to use your own manual saves.
Finished the game and, as far as I experienced, there is no recollection release. Considering how recollection is done for the game, I guess it makes sense. I guess I just have to hunt for other events without knowing if I got them all... unless there really is an unlock all I don't know about?
