editing to ask this, where are you in the story at the moment? cause some of the scenes are locked behind other quests being completed.
wait the sawmill scene? do you mean the one that has a CG with Barrel or the one where the MC fucks him at night? because that one is unlocked by just beating Scar and checking his (Logan's) house after doing the visit at your house from Jester during the night. and on the other thing, that's strange, I can't tell if it's something we're forgetting or just RNG being hell I'm gonna see if I can get the scene on my bottom saves to figure out if I can just trigger it by loading in or if I'm also missing something.
second edit to add, I checked and got the scene literally right away. on this save I'm actually incredibly behind the main story and only have the bareshade expansion, curse of lust, country road, full moon and between worlds event. have you finished any of those?
