I take your point about not asking consent first, it isn't offered as an option however, otherwise I would choose that, absolutely.
For me, and I know I'm likely to be in the minority here, the original reaction rang true to the rogue vampire my Tav came to know and love. I'm not wanting Larian to change this development (it does feels to me like patched in morality like the patch 6 kisses were), I'm just hoping for a Mod that will give me the roleplay I want and enjoyed with my Tav on earlier playthrough.
It did glitch for me too, Astarion walked in, Mizora out and then we suddenly teleported to where we were before we went to bed. Wyll gave me a lecture though.
I suppose in my head, I had seen the full dialogue on youtube and that became cannon for me, guessing my game just had a glitch, not knowing others had this glitch too.
Does Shadowheart still allow the night with Mizora though in Patch 7?
