*Warning Spoilers* This bug has occurred for multiple users and removes an entire feature from the game.

After the quest "The Disappearing Act" quest is complete Dr. Crocker is dead and shortly after Dr. Sun approaches the player and informs the player the mega-surgery center is reopening and he is resuming Dr. Crocker's operations. However, the dialogue option for facial reconstruction isn't there, instead the original option of "Other Procedures?" is there. Furthermore Dr. Sun vanishes or no longer can be found at his shop a few in game days after the quest.

I have a suspicion that a couple items cause this: 1. Dr. Crocker facial reconstructive surgery is a side quest that can be failed and in my case it was failed because I figured I can always visit him later, not realizing this quest kills him. 2. Dr. Sun states he is going to tell the proper authorities or something my guess is every time the player enters diamond city this script launches.

Please fix this Bethesda. This ruins an entire option within game since no other NPC can provide this service. No offense Bethesda, I love you, but it was pretty stupid to have one NPC that dies be the only one able to provide a service. This quest outcome isn't a choice either making it rather unfair for the player. Please take your time in developing your games, your level of detail in development is the reason we all love you.
