When I complete the quest, "The Moon Comes Over the Tower", which involves bugging Mr. House's computer for the Followers of the Apocolypse, the little square next to the current objective on the quests screen, on the pip-boy, doesn't colour in and the quest is still marked as active.

Click this link for a better understanding. Its a picture of the problem im talking about.

As you can see the quest is completed yet the square hasn't been filled in and the "Show Location" is still highlighted.

Anyone know how to solve this?

The quest is not still marked as active. As you can see, the quest is darkened, it's finished. I actually don't see a problem here at all.

It's just annoying looking at it. It ruins a nice page of finished quests. If there is anyway to remove it I would be thankful. Or I could load and approach the quest differently if that would get rid of it.
