Wept for Zion
You know that quest for some ghoul chick to go through some underground passage by using a custom eyebot that sends out some sort of signal that turns rock to dust? (least I think it was that quest)
Yes, that was a quest, "The Big Dig", AKA the most glitchy quest I've ever seen. I've honestly never had any bug problems in 3 or New Vegas but this was my first major bug from the Fallout series. Essentially the ginger guy that owns the eyebot you were referring to just kept randomly going hostile for no reason, despite the fact I never shot him. Unfortunately he was marked essential, so I couldn't kill him. So I was stuck with this immortal bastard trying to shoot me every 5 seconds, and my last save was from like 30 minutes ago so I couldn't really go back. Eventually I fixed it by using the console to kill both him and Bobbi (the ghoul) at least 40 times before they both finally stopped aggro'ing. It was so frustrating. That's not even to mention the fact that the end of the mission glitched and wouldn't let me finish it because Bobbi broke. I had to use the console to end it.
