Hello all,

I recently started playing New Vegas again (In preparation for the "Old World Blues" DLC which is coming out soon) and am stuck on this particular mission (House Always wins IV), this is because despite compleating it I cannot "hand in" the quest to Mr. House and so cannot compleate the quest. I know I could fail the quest by shooting up the casino and so lowering my reputation, but I don't want to do that for obvious reasons. I haven't found a solution to it anywhere, and restarting the game doesn't help the problem go away.

OS; Windows 7 64-bit Ultimate
CPU; Intel E8500 Dual Core @ 3.16Ghz
GPU; Nvidia 260GTX
RAM; 4GB DDR2
Game version; Current Steam Build

I have a screenshot of the issue here; http://imageshack.us/photo/my-images/233/2011071100001.jpg
