Forum:How little we know, Cachino Bugged

Long story short: I am really stuck, Cachino seems to be bugged, tried 4 different ways through and still bugged

-details-

I am on The House Always Wins IV - (deal with omertas) and which coincides with How Little We Know.

So I have followed the walk through, and at the part where Cachino and you are supposed to go have a meeting with the bosses. I tried the speech method where he will come and shoot with you and the other one where he just passes you a gun. Each method results in him just standing there, when I try and talk to him again he says "Its time for the meeting with the bosses I cant chit chat right now" I go to the bosses and they dont want to say anything than what they wanted to say to me before I go to this point.

I have repeated the quest three times, ie having Troike blow up the guns himself, getting proof for Troike he was set up, and setting off the thermite my self. I have tried exiting the casino, waiting 3 hours, coming back in and Cachino is still just there saying "Its time for the meeting with the bosses I cant chit chat right now".

Getting sick off all this I even killed EVERY ormerta, making sure to not kill the innocent and killing all named characters.

None of these options work. I am dead in the water now on the House quest chain.

Any help?

--Update-

I went back in saves just before I turned in part 3, and went straight to the omertas and massacred them all after that, its the only way I could get this quest done. Are bugs like this normal? I had a similar experience with the Kahns and Boomers.
