Unofficial Fallout 4 Patch

TLDR; The "A Magical Kingdom" quest isn't tracking properly. I'm playing on Xbox Series S

I'm experiencing a pretty substantial bug with the "A Magical Kingdom" quest in Nuka-World. I entered Kiddie Kingdom and heard the various voice lines from Oswald. I was then told to search the Tunnels, Fun house, and Theater. I found the Tunnel entrance and saw Oswald talking to a ghoul. Oswald then vanished, I killed the ghoul and turned off the gas pumps.

After that, I stumbled upon the Theater and entered. Oswald appeared and started talking. I shot Oswald before he finished talking, and he attacked. I regretted that and reloaded my save from when I first entered the Theater. I listened to his speech, he raised the ghouls around me and I killed them and then defeated Oswald. He vanished and nothing else happened. I explored a little more and found the elevator, which said that I wasn't functional.

I then left and found the Fun house. I went through the maze, and came upon the conveyor belts and saw Oswald in the window above. He was leaning over a control panel staring at me. As I got closer, a grenade fell from the ceiling which I avoided. I then went through the remainder of the Fun house and found the control room that Oswald was in. He turned around and looked at me, but didn't say anything. I moved around a bit to try to activate his voice lines, but nothing. I shot him and he immediately vanished and said something along the lines of "you really thought it would be that easy?". At this point, my pip boy said the only thing left to explore was the Fun house. I wandered around the Fun house a bit more, but nothing else happened. I then went back to the Theater and nothing happened. The elevator was still not working. I went back to the Tunnels and Oswald was standing in his control room alone. I approached and he said nothing. I shot him and he vanished and said the same line "you really thought it would be that easy?"
