I've activated the console on the top of the tower, and triggered the dialog with Elijah, Christine, God and Dean. The fireworks start, but the quest log still says I have to trigger the gala event. The map also points back to the tower. Is there any way to fix this?
Tried doing Dead Money from the Bunker. Same problems. I went back to the fountain after the gala event was triggered, and the casino gates were locked. I used the console command 'unlock' so I could continue to the next part. It gave me 'Put the Beast Down', which the wiki says is directly after 'Trigger the Gala Event'. This (hopefully) shouldn't cause any problems.
