Bugs

 * After eliminating the Omertas, Mr. House doesn't recognize that they are gone. To remedy this, load a save point before killing Big Sal and Nero, go talk to Mr. House and make sure you go through all the dialogue on what to do about the Omertas. After this, killing Big Sal and Nero and returning to Mr. House should allow you to finish the quest.
 * There will be an option while talking to the Omerta receptionist that says [Barter x/55], meaning you need at least 55 Barter to choose it. But upon using a Salesman Weekly to raise Barter to 55, the option goes away, and you are left with the [Strength x/8] option or the option to hand over 300 caps. Leveling up the Barter skill does not help.
