Investment portfolio helpdesk

I am working on a helpdesk at the moment - assisting about 8 investment gurus who are managing about $20 billion between them. Today I had to find $94 million that was missing. Wasn't much. Fortunately someone had just entered a couple of $10 million dollar payments twice and then the other $50 million was another double count due to a complication in calcuating portfiolio size.
Ended up alright.
The worst thing was the fact that the connection to the trading server was lost in the middle of the reconciliation and we had to reconnect.
