So Ive been really lucky so far, but finally I have encountered my first few game ruining bugs. It's my second play through and I'm trying to finish all companion quests before i proceed to the final quest. Problem is, most of the quests have bugged. I managed to complete ED-E, Rex, Lilly and Boones, but Raul, Arcade Gannon and Veronica aren't playing ball.

First lets look at Veronica:

The quest went fine up until the point where I must return to the elder with the tech. I'd already completed both the vault 22 quest and the Helios one quests (The data wasnt destroyed in the former but Archimedes II wasn't armed in the latter) so I picked the obvious option and recovered the pulse gun. But i've encountered a bug that apparently alot of people have already encountered, as soon as Veronica and the elder are face to face they start a staring contest instead of a quest progressing conversation (although the elder does make a movement that would suggest he soiled himself, which does please me somewhat). I've tried a few fix' on the wiki (dropping the weapon, re-downloading the info from gibsons shack etc) but none worked, so would anybody else suggest something to help or something that worked for them?

Arcade:

I managed to trigger about 90% of his conversation but he still isn't initiating the companion quest. Any ideas?

Raul:

I'm having trouble even initiating the triggers for his quest, the only person he responded to was sterling, ranger andy having already been spoken to and Loyal having no conversation options other than "goodbye", ha anybody ele encountered this?

I'm almost dreading getting cass as a follower after experiencing these ultimately dissapointing bugs.

For Arcade i think you have to be just before the battle of hover dam before his quest is initiated. if your going for mr house, yes man, NCR, or legion you need to do the quests all the way up until the battle of Hover dam then he should talk to you and tell you his story. I have no idea about Raul's quest as i have never done it. I hope anything i said kinda helped even remotely. Good luck sir/ma'am.

Cass should be easy, her tirggers are all self contained really, unlike Boone, ED-E and Veronica.

How the hell did you do the ED-E quest???
