I've been enjoying the game so far, however I have came to a halt in the main quest-line, more specifically, the 'Wild-Card' quests.

I originally started with Mr. House's quests. I went to The Fort to get the Platinum Chip and killed everyone on site, including Ceaser. I then released Benny just to immediately kill him as he ran off, I can't remember who dropped the Chip, but I had it. I then took it to Mr. House who upgraded the Securitrons, but then decided to kill Mr. House straight after and follow Yes Man's quests.

Now I am stuck as I need to go to The Forts hidden bunker, but I do not have the chip anymore. I still have the 'Change in Management' quest activated too, but there are no directions given in it.

Any help is appreciated. Thank you.
