Customer adress error

[havegang]

Hi
Today i got an order, where invoice- and shipping adress belongs to another customer.
Both customers are registered long time ago and there's no history of any troubles with their user accounts.

I checked Id's in both Customers and Adress for coincidences - no luck.
And for now its only one order, where this error is found.

Is it possible to query the order in my db?

Thanks in advance.
