I'm going to say that it was because of a lack of storing procedures at the time to deal with the specific type of artifact. Maybe something happened on site and it was decided to temporarily move them until the issue resolved itself. I imagine Walt had retired at that point and agreed to safeguard them. He was one of the richest and most influential people associated with the Warehouse by that point.

If we assume he became associated with the Warehouse sometime in the 30s, the dates match up enough for him to have the vault built with in the animation studio in Burbank. After the artist strike in the 40s being caused by the build-up of energy they were relocated to the first Disneyworld which was built in 55 but first drafted in 48.

While there, the artifacts energy was able to affect the visitors in a more positive way and it was decided that there was no further need to move them again. As for the retrieval, after the incidents with Sykes, Paracelcus and Guichon it was likely deemed that in a modern climate, with so many equally influential enemies of the Warehosue, it wasn't safe to store so many off-site. And with enough agents to spare and no immediate threats the timing was ideal for a covert retrieval. I'm imagining current owners have no idea the vault exists, so simply going up and asking isn't an option.

As for who goes, Still Aden and Felix, obviously. They seem to do a lot of missions together. Maybe Megan, if we decide she's around by then (shotly after the Guichon incident). Maybe Joe, if he's sticking around. Maybe Pete or Myka, if we want to actually include some oft-forgotten canons.
