Should I put off going into Vault 11? I like to side with Mr. House, but I read that there is a turret inside vault 11 mistakenly placed into the 'Lucky38' faction, which automatically fails 'The House Always Wins' quests. So my question is, should put this off until I complete said quest?

There IS a turret that is in the Lucky 38 faction so, if you want to follow the story line of Mr. House (like I did in first place) I wouldn't recommend you to go there

Oh I've already completed Mr. Houses quest. His is just my favorite by far. :laugh: (and he's my favorite NPC in the Fallout Franchise)

I went to Vault 11 long before I got anywhere near the Strip and killed said turrets/robots and have not encountered any troubles at The Lucky 38 what-so-ever. I'm currently in the middle of The House Always Wins (well not long started it truth be told).
