I don't know if anyone has written about this, but right now there is still an Araj Oblodra potion loophole in the game.
If you kill Yugir first and get a confession from Astarion, you can then go to Oblodra and get Astarion to bite her. The relationship doesn't end, you only get a little disapproval from Astarion and the potion, which is wrong in my opinion.
There should be consequences for these actions. I think it would be better if if, if forced, it triggered a scene where it expressed its opinion to the player or ended the relationship, if there is one.
I agree. I consider this an even worse betrayal to him after the romance is locked in than before.
This is also one of the reasons why I would have preferred the post-Araj scene to be separate from the confession scene and not be used as an alternate romance lock-in. Furthermore, you are missing out on an important character development moment for Astarion if you lock in the romance before you meet Araj and thus never get the post-Araj scene.
I reported this exploit bug to Larian a couple months ago and they told me they were aware of this issue and already working on it and that it wasn't intentional, so hopefully we'll get a fix
