I mean you are kinda lying dude. For example look at the v0.5.7.8 and v0.5.8.0 update:
Continued content for the sharing route for Claire & Bjorn (4 animations) in v0.5.7.8
Continued content for the sharing route for Claire & Bjorn (4 animations) v0.5.8.0
So what are the new vanilla-harem scenes in that updates in counter those ntr-sharing scenes? Also this Bjorn fella has another scene with the Girl Carmen just before this exact updates
You went out of your way to prove how wrong you are. First you went back like 7 or 8 updates to even find what you claim is happening in every update. Further those updates also included: (really they started in v05.7.5 and you can see Chyos talking about how those minor updates happened 7 days apart from each other.)
You get a new sex scene with Kate on your way to the Old Boar. She rides you in the caravan with Claire watching.
At the old boar you get a new character Carmen, you have your choice of three rooms with her, a hj, bj, you give oral and couple of other sex scenes with her. So five or six vanilla scenes, strictly vanilla. (except you are making her cheat on Bjorn, so you are probably crying about that.)
You get a scene where Kate wakes you up in bed with a BJ.
You get a threeway with Kate and Claire in their bedroom.
You get to finger Claire's vag or ass on the balcony, you can then later fuck her in either hole (ass takes another few steps). You can chose to put Bjorn in position to see it or not. When you wake up in the morning, which is before Claire, you can go downstairs and talk to Carmen, which sends Bjorn upstairs. Then at 9 am you play with Claire on the balcony. If you made Bjorn go upstairs he watches, if you don't chose to make him go upstairs, he doesn't watch.
You can stop fingering her, and move the sex to your room, not NTR involved.
Or you can do a chain events that allows you to bring that new sex scene to Bjorn's room. From there you can do steps to allow Bjorn to first watch, then later join in. It's the same scene that can happen in your bedroom, but now it just happens in Bjorn's room with Bjorn getting a BJ will you are behind her.
So of the animation frames, that update has like 4 frames that have NTR sharing in it, and you can get those exact same frames (which are new to Vanilla players) that are just the MC.
You really shouldn't project your nightmares onto a changelog, because the reality is that the changelog does not reflect your fears.
