Chapter 1 or 2 where you're at a campfire with Virion, the background of the camp is all rainbow color and glitchy. Then in chapter 6 is a really weird glitch. I got a romance scene with Argandea where I pin him down to the bed and stuff when I didn't romance him but not when I did.
Also, I don't know if it's also a bug or not, but if you romance Raelan, Virion has some huge love confession and then when you see Argandea they talk about how they have a relationship so idk if that's intentional or not. Was just kinda odd.
ETA: Ah, overlaps with ChaoticAngel's comment. Yes, that also happened to me. I was also romancing Virion, so idk if it's a thing specific with him (didn't happen when I romanced Raelan), but I'm guessing it just somehow switched things up and tagged the romance scene as friendship and the friendship scene as romance.
