When and How Did That Happen? UPDATE Picture

I have used the stand alone vault for some time now. It's just easier for my young Global Superstar who still lives with his parents and siblings, to keep track of his earnings overall. He now has very close to half a million Simoleons inside that box. Tonight, after his Charity Event, I had him go to the vault to secure what he earned the day before, plus the day's earnings, as well. As I click on the vault, I get the message about the vault and it reads that it's secured for Brianna Cantrell, and then the amount is listed below the name. I'm thinking, say what? When and how did she get control of the safe? She's asleep, and that's perhaps why when I made her the active Sim that she couldn't open said vault. Because, when I had Erik attempt to open it, suddenly an alarm goes off. When and how did the transfer take place? Also, I should mention I noticed he had the option to break in. That was my first clue something was amiss. :o Has anyone else had that happen, or do I have a punk teen girl trying to steal her older brother's Simoleons? Is there any way to make it his vault again?

Has this bizarre occurrence ever happened to anyone?

I do realize I could purchase another vault, and cheat the amount of money for Erik to put into it, but it's very weird that suddenly the vault belongs to his younger sister. :| And totally messed up. :/

Please, and thank you, in advance for any advise on resolving this issue.

Resolved it: I had Erik simply break in, after he attempted to open it on his own three times and got the alarm.

Then once he got it open, he simply removed the money. I moved the vault to another location, bought a new vault and had him return the proper amount to the vault, plus the two days' worth of earnings. Once that was accomplished, I had him donate the other vault to a fan. :D :D :D :*
