Bug at the end of "how little we know"

[LostToTheZone]

I hope to find someone who can help me to solve an incredible bug of this quest.
I take these quests in this order: "wild card side bets" and "bye bye love". I've completed the second one and i've begun "how little we know". I've chosen Cachino's side, It's all gone well until the final meeting with big sal and the other guy. Everything i do (using eloquence to convince Cachino to shoot or convincing big sal of being betrayed or simply shooting) the result is always the same: after the shooting i'm stuck inside the meeting room and i can't talk to cachino to end the quest. I've also tried to follow the order of every step in the official guide, but nothing has worked.

Did you kill Nero(I think that was his name) the second in command also? I believe you need to kill both in order to complete quest.

Also what do you mean stuck in the meeting room? Do you mean you can't move or the door is locked? If the door is locked go to console commands (~ key) and then click on door and type "unlock". If you can't move go to console commands and "enableplayercontrols" (use during moments such as cutscenes).

Yes, i kill Nero. I think to a bug because if i kill big sal, nero or even cachino nothing happens. But if i kill the guy who checks weapons at the entrance, the quest fail.
In some occasion the door remains locked, but i think there's a misunderstanding, maybe i've used the wrong word. I mean stuck with the quest, because nothing happens after i kill big sal and nero: quest remains active and the marker on Cachino is always active.

Try to move Cachino from his spot and hope that it will activate his dialogue. (Example: walk into him and physically push him possibly toward door).

I'll try. Before or after the shooting?

Probably try after shooting. Also I will be back in about 30 min if you have anymore questions.

I've just tried to move Cachino but he begins to move to come back to his initial position

Well I am out of ideas if he won't talk to you.

No matter, thanks.

EDIT: In a previous game I've already have a similar problem with Ranger Grant (quest "You'll know when it happens") but i've solved with with "kill" and "resurrect" + setstage commands. I would like to try on Cachino (even if i wouldn't know how to use setstage), but now i'm in hardcore mode and i'm afraid to lose the achievement if i use them.
