I remembered from previous PT's you'd get in trouble if you didn't coddle up to the brats, but I didn't remember it was so hard to convince the tieflings of your good faith
To be fair, you don't really need to coddle up to them. Just help 1 of them and don't tell Mol off and they're fine. Anything else is just if you want to do it.
Also, why is the deception proficiencey bonus from cha not being counted in this roll ? That still looks buggy.
I don't know.
Without any logs regarding the roll and statuses regarding the party it's hard to say what or where the bug might be. (Whether it's specific to this particular dialogue interaction or something more generic)
From the information you've provided my gut instinct is asking "Did Wyll
actually make the roll?"
As from the context you provided, it is suggested that Guex confronting your party was a surprise. Meaning you didn't pre-organize your party to enter the dialogue. Then given that you cannot simply back out of this dialogue and re-engage it later. I wonder how you managed to "Let Wyll do the roll", when the game defaults to the Player Character in dialogues (Meaning your Durge would be the one doing the dialogue options and any skill checks) unless they're specifically positioned very far away when the dialogue is initiated.
