I am having a major storyline bug that is preventing and form of progression. I decided to go the Yes Man route till the very end (right before I choose the Act III mission for Yes Man). I then decided I wanted to go NCR and went to speak to the Ambassador. After completing all the missions up to protecting the President I noticed a INSANELY UN-MISSABLE bug. If you protect the President going down the Yes Man route, it will glitch and you will not be able to complete the NCR missions. This is a major bug and should of been fixed in your entire workflow before release. If anything, it should register with NCR that you already protected the President and move on within the storyline (Act III). If it does not do that, then you should not be able to speak to the Ambassador regarding mission progression with the NCR.

You once again failed Bethesda... I am frustrated with your inability to create a stable game for the price we paid. I can understand freezing and glitching, yes it's frustrating but the game is massive and runs on an already determined unstable engine. But, to have your storyline have so many faults including a Main Quest game breaking bug... That is 100% all on your end and cannot pass the blame on anyone else.

I smell a class action lawsuit coming your way if you do not satisfy the requests of your faithful customers...

This is bad. Makes me wonder how to proceed, as I'm near the end.

I'm stuck waaaaaaaaaaaaaaaaay back.
With the Brotherhood of Steel, I can't [censored] contiune because the quest is [censored] bugged.

Dude I feel your pain. I'm in the same situation that your in. I protected the presidents stupid self thru yes man. But I did notice that after I successfully protected him it told me to go talk to the ranger guy but I couldn't interact with him. I cant even pickpocket him. I can move him out of the way until he runs back into place. So I just ignored it and moved on to the NCR part 2 line. I got the BoS to aid me in the battle. I then went back to tell the dam's leader and she moved strait into you need to protect the president. So theres nothing I could do about it. I cant even fast travel. My closest pre mission save is an hour back.

It just really pisses me off that I cant have the BoS fighting by my side now. My only glimmer of hope is that my pre mission save was before I did the president for Yes man.

I'm honestly scared to continue the main story due to the glitches and the 3-4 paths you can take.I want to take the good way on this playthru but i have no idea what affects what. and from what i've read,once you make the choice of benny/yesman/house the story gets locked on track and you can't get out of it.
