Okay so I just arrived at the Strip and Victor asked me to go to the Lucky 38 to speak with House. As soon as I walk in the front door I'm attacked by the Securitrons. I battle my way through the Penthouse to where House is and when I talk to him he says something like "Why didn't you do as asked?". Clearly I've managed to jump some plotflags here. Only thing I can think of that might have caused this is that I explored the H&H tools building on my own and there was a lot of House related stuff in there including a Lucky 38 keycard.

Is there anyway to manually set the plot flag back or something in order to fix this issue? I'd rather not start over 24 hours into the game.

I have the exact same problem. I have just reached the strip after I have reached level 30 and visited all locations on the map, saving the strip for last, finally making it only to speak with Victor, then find his body outside the Lucky 38 casino, then entering to have all securitron bots turn hostile and attack me. My brother is also playing but he does not have this issue, when I mentioned it to him, he told me you enter the Lucky 38 and simply speak with Mr House. I am eagerly awaiting a fix to this solution as it kind of stops me from proceeding any further...

My guess is our best hope is for someone who knows a little bit about modding to stop by and give us the magical console command to set the proper plot flag.

Looks like I've managed to resolve the issue.

From what I've gathered, the Turrets at the end of Vault 11 are the same faction as The Lucky38, causing them to attack you on site.


In order to stop them from attacking you, enter the following into the console.

setally 001267AB 0001B24A 0 0

OK, I loaded my game to be just outside the strip, opened the console, typed in the following...

setally 001267AB 0001B2A4 0 0

Then entered the strip and spoke to victor, then approached and entered the Lucky 38 Casino, and yay, the securitrons did not attack me.
So I spoke to Victor and went up to the penthouse. Exited the elevator and spokje to Jane, exhausted all avenues of speech, sold 3 snow globes.
I then head down to the mass of screens to speak with mr house.
Unfortunately, I cannot speak with mr house. The cursor recognises the screens as Mr House, but when I try and interact, nothing happens...

I found on Nexus a mod, called Vault 11 House Wins Fix.

The description for which reads...

"Some of you may have noticed that when you complete Vault 11 and kill the turrets and Robots at the end, you fail the quest, "The House Always Wins". This is because the turrets in Vault 11 were affiliated with the Lucky 38 casino, which must have been an oversight by Obsidian.

This patch removes the turrets' affiliation and allows you to complete Vault 11 without fear that Mr. House will get his revenge for destroying his arbitrary turrets. "

Unfortunately I have no idea how far back I would have to load, in order to be able to do vault 11 again. This may help others, but I am too far into the game to be trying to load back. I just need another console command I can type in, to get Mr House talking.
I am level 30 and have visited every location on the map, saving the Strip for last...
